                                    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. nhiaya  |
