A point positive charge is brought near an isolated conducting sphere (Fig. 1.2). The electric field is best given by
A. Fig (i)
B. Fig (ii)
C. Fig (iii)
D. Fig (iv)
The answer is the option (a)
Explanation: The electric field lines are always perpendicular to the conducting surface. There are no lines inside the conducting surface, and the electric field lines are always coming out of positive charge and goes into a negative charge. Therefore (a) is the correct answer.
