A solid sphere rolls down two different inclined planes of the same heights but different angles of inclination. Will it reach the bottom with the same speed in each case? Will it take longer to roll down one plane than the other? If so, which one and why?

1.	A solid sphere rolls down two different inclined planes of the same heights but different angles of inclination. Will it reach the bottom with the same speed in each case? Will it take longer to roll down one plane than the other? If so, which one and why?
Answer» Solution :V must be the same i.e. it will reach the bottom with the same speed. TIME TAKEN will be LESS for the plane of larger angle as `t=(1)/(sintheta)`
