A block of mass ma is suspended vertically with a spring of spring constant k. The block is made to oscillate in a gravitation field. Its time period is fould to be T. Now the space between the plates is made gravity free, and an electric field E is produced in the downward direction. Now the block is given a charge q. the new time period of oscillation is   img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V03_C01_E01_129_Q01.png" width="80%"
