A conducting shell having total charge 4C is placed inside a uniform EF of 60 N/C. Net force on 2C charge placed inside shell is and conductor is held fixed. Then select CORRECT options.
Options:(select one or more)
Answer:
B, D
Solution:
Given net force on the internal charge is -30 N.
Therefore force due to the shell is -150 N, so B is correct.
The external field is screened inside the cavity; induced charge on inner surface supplies the given -30 N contribution, so D is correct.
