Two particles are moving in circular paths of radir, and r2 with same angular speeds. Then the ratioof their centripetal acceleration is46.(2) r, :互thle(3) r2 : r,(4)小時

Answer»

The formula for centripetal force is

F = mv²/R

sub. v =rw(omega)

F =m r w²

w (angular velocity) will be same as the time period is same......

F1 = m R1 W²

F2 = m R2W²

W(angular velocity) and mass are constant.

F1/F2 = R1/R2.

:- The ratio is R1 :R2.
