Question

If body P, with positive charge, is placed in contact with body Q (initially uncharged), what will be the nature of the charge left on Q? A. Must be equal in magnitude to that on P. B. Must be negative C. Must be positive D. Must be greater in magnitude than that on P A free electron is in an electric field. With respect to the field, it experiences a force acting: A. Parallel B. Anti-parallel (opposite in direction) C. Perpendicular D. Along a constant potential line The diagram below shows a positively charged plate and a negative point charge. The electric field line pattern for this situation is best shown by

Explanation / Answer

1)

here,

when they are in contact the potential of both P and Q is same

as the shape of bodies is not same

the magnitude of charge is not calculated

so, the charge on Q is positive

correct option is C) Must be positive
