D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: D
Solution :
When a metal piece falls from a certain height then eddy currents are produced in it due to earth?s magnetic field. Eddy current oppose the motion of piece. Hence metal piece falls with a smaller acceleration (as compared to g). But no eddy current are produced in non-metal piece, hence it drops with acceleration due to gravity. Therefore non-metal piece will reach the earth?s surface earlier.
