A block of mass 2 kg executes SHM on a smooth horizontal plane under the action of restoring force of a spring. If the amplitude and time period of oscillation are 0.05 m and `pi//5` second, the maximum force exerted by the spring on the block isA. 5 NB. 10 NC. 100 ND. 19.6 N |
Answer» Correct Answer - B `omega=(2pi)/(T)=(2pi)/(pi//5)` `omega=10" rad/s"` `F=momega^(2)A` `=2xx10^(2)xx0.05` `=10N` |
