JEE Main 2016 — Electrostatics 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
=
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
=
