Answer 41: c.

Answer 42: d

(Hint: Force on Q due to E is QE and not zero. Force on Q is zero due to E & electric field of induced outer charges on sphere. Charge density on inner surface is not uniform therefore net force on charge Q is not zero. Due to E, net force on shell is zero because net charge on shell is zero.)
