A point charge q_1 is placed inside cavity 1 and another point charge q_2 is inside cavity 2. A point charge q is placed outside the conductor. For the situation described above, answer the following questions. If charge q_2 is at point Q (inside cavity 2), then vecE at the center of cavity 2 due to induced charge on the surface of cavity 2 would be

Answer»

`q_2//(4piepsilon_0r'_(2)^(2))` toward `q_2`
`q_2//(4piepsilon_0r_(2)^(2))` AWAY from`q_2`
zero
cannot be determined

Solution :if `q_(2)` is at POINT Q then INDUCED charge `-q_(2)` would be non-uniformly distributed. So, we cannot determine E due to `-q_(2)` at any inside point.
