Question

An ideal pendulum oscillates in vaccum between two extreme positions a and b if it goes from position a to position b and then returns from b to mean position c in 3 second then it will complete 3.5 oscillations in

Answer 1

Here time taken in moving from A to C via B.=T/2+T/4=3T/4 s.As per question 3T/4=3s=> T=4s. So 3.5 oscillations will take 3.5×4=14s.Ans…
