1.	A solid iron sphere `A` rolls down an inclined plane. While an identical hollow sphere `B` of same mass sides down the plane in a frictionless manner. At the bottom of the inclined plane, the total kinetic energy of sphere `A` is.A. less than that of `B`B. equal to that of `B`C. more than that of `B`D. Sometimes more and sometimes less
Answer» Correct Answer - B In both the cases the loss of gravitational potential energy and the resulting gain total kinetic energy is same.
