An electric field converges at the origin whose magnitude is given by the expression E=100 r N/C, where r is the distance measured from the origin.Hint: The dimensional formula of electric field intensity can be found by using the dimensions of force and charge, as electric field intensity is the force per unit coulomb. Mathematically, $E=\dfrac{F}{q}$ , where E is electric field intensity, F is the force exerted on charge and q is charge.Radial Coordinate System: The electric field of a point charge is defined in radial coordinates. The positive r direction points away from the origin, and the negative r direction points toward the origin. The electric field of a point charge is symmetric with respect to the θ direction.

What is E kQ R 2?
the magnitude of the electric field (E) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation E = kQ/r2, where k is a constant with a value of 8.99 x 109 N m2/C2.
Is electric field intensity and electric field same?
electric field, an electric property associated with each point in space when charge is present in any form. The magnitude and direction of the electric field are expressed by the value of E, called electric field strength or electric field intensity or simply the electric field.
How do you find the electric field at point P?
Find the electric field E at point P (as shown in the figure) on the perpendicular bisector of a uniformly charged thin wire of length L carrying a charge Q. The distance of the point P from the centre of the rod is a = (√3/2)L.
What will be the electric field at O if the charge from one of the corners is removed?
Thus, due to symmetry, the forces due to all the charges are cancelled out. As a result electric field at O is zero.
What is electric field intensity?
A measure of the force exerted by one charged body on another. Imaginary lines of force or electric field lines originate (by convention) on positive charges and terminate on negative charges.

At which location is the electric field intensity equal to zero?
In Region II, between the charges, both vectors point in the same direction so there is no possibility of cancelling out. In Region III, the fields again point in opposite directions and there is a point where their magnitudes are the same. It is at this point where the net electric field is zero.
Is V m the same as N C?
Units for electric potential and fields
But a “Joule per Coulomb” (J/C) is also known as a volt (V), and the electric potential is thus often referred to as the voltage. The electric field can therefore also be quoted in units of volts per meter, since V/m = N/C.
What is relation between E and V?
Therefore V2=6E, which is the required relation between ‘V’ and ‘E’. Note: Students should always remember that electric potential is a scalar quantity whereas the electric field is a vector quantity. The direction of electric field lines is always along the direction of decreasing electric potential.
What is the relation between electric field intensity and potential gradient?
Relation between Electric Intensity and Potential Gradient. The change of electric potential with respect to distance is called potential gradient. It is denoted by dv/dx. hence, the negative of potential gradient is equal with electric field intensity.
How do you find the electric field between two plates?
How to find the electric field between two plates? The electric field between two oppositely charged plates can be calculated: E=V/d. Divide the voltage or potential difference between the two plates by the distance between the plates. The SI units are V in volts(V), d in meters (m), and E in V/m.

What is the electric field between two opposite charges?
If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity.
