The radii of two metallic spheres `P` and `Q` are `r_(1)` and `r_(2)`, respectively. They are given the same charge. If `r_(1) gt r_(2)` then on connecting them with a thin wire, the charge will flow

Options

A. from P to Q
B. from Q to P
C. neither the charge will flow from P to Q nor from to `P`
D. The informations is incomplate

Answer

D

Explanation

Since charge flows from high potential to lower potential.
If positive charge is given, then `V_(1) lt V_(2) as r_(1) gt r_(2)`
So positive charge flows from `Q rarr P`
If nagative charge is given, then `V_(1) gt V_(2)`
So negative charge flows from `P rarr Q`.
Since it is not given that whether the charge given is positive or negative, henace the information is incomplate.
