JEE Main 2016Electrostatics Question with Solution

From: JEE Main 2016 (Online) 9th April Morning Slot

Question

The potential (in volts) of a charge distribution is given by.

V(z) = 30 5x2 for 1 m.
V(z) = 35 10 for 1 m.

V(z) does not depend on x and y. If this potential is generated by a constant charge per unit volume (in units of ) which is spread over a certain region, then choose the correct statement.

Correct answer
A = 10 for 1 m and elsewhere

Step-by-step explanation

We know,

E(z) =

   E(z) = 10 z for m

and E(z) = 10 for m

   The source is an infinity large non conducting thick of thickness z = 2 m.

   E = = =

    = 10

    =
