Question

Q.1DRAW THE ELECTRIC FIELD vs DISTANCE (from the centre) GRAPH FOR
(I) A LONG CHARGED ROD HAVING LINEAR CHARGE DENSITY < 0
(II) SPHERICAL SHELL OF RADIUS R AND CHARGE Q > 0

Answer 1

for spherical shell..............

Answer 2

Answer: for a long charged rod The graph of E vs r with λ < 0 is shown in below graph

Explanation:

The electric field for a long charged rod having linear charge density λ is given as  1/4*pi*epsilon*lambda/r

Hence, E is inversely proportional to r.
