its isnt given that plate is grounded
Ques1) A conducting sphere is placed between two charged par- allel plates . Does the electric field inside the sphere depend on precisely where between the plates the sphere is placed? What about the electric potential inside the sphere? Do the answers to these questions depend on whether or not there is a net charge on the sphere?
Ques2) A positive point charge is placed near a very large con- ducting plane. A professor of physics asserted that the field caused by this configuration is the same as would be obtained by remov- ing the plane and placing a negative point charge of equal magni- tude in the mirror-image position behind the initial position of the plane. Is this correct?

The professor is correct in saying the statement.
The situation given is like this
Note that the plate is grounded
Some charge will be induced on the conductor because of the charge. As a result, the infinite plate will also induce field and potential at different points..
since the plate is a conductor and is grounded, the potential of the plate is 0.
charge induced on the conducting plate which is grounded are the same.
Hence we can replace the case of of the conducting plate with that of dipole. Answer will be the same.

I didn't read the question, yet again!!!!!!!
This the question a was taught recently
