Question

an ideal pendulum oscillates

in vacuum between two extreme positions A and B.

If it goes from position A to position B and then

returns from position B to mean position C in 3 s,

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…
