answer with explaination

Answer 1

Answer is (c) unchanged

Answer 2

HEY MATE!!! ❤❤❤HERE'S UR ANSWER!! Option (C) Unchanged. EXPLAINATION ---The metal plate, being a good conductor, will have its electrons rearrange in such a way as to neutralise the electric field inside the plate.

The electrons would tend to bunch up in the plate at the point(s) closest to each of the two charges, alterring the electric field that they're exposed to and changing the electrostatic force on them.

Strictly speaking however, the force applied by one charge to the other remains the same. But the force that each particle experiences will be reduced by the partial cancellation of the positive field by the proximal electrons bunched up in the plate.
HOPE THIS HELPS YOU!!!
