1.

In the figure given below, an ideal pendulum oscillatesin vacuum between two extreme positions A and B.If it goes from position A to position B and therreturns from position B to mean position C in 3 s,then it will complete 3.5 oscillations in(1) 14 s(3) 1.14s(2) 4 S(4) 2 s

Answer»

0.5oscillation =3sthen 3.5 =7 times 0.5then 7*2=14secmultiplier is 2 as oscillations are to and fro
