Question

A particle executing SHM crosses points A and B with the same velocity. Having taken 3 s in passing from A to B, it returns to B after another 3s. The time period is

(a) 15s 

(b) 6s 

(c) 12s 

(d) 9s

Answer 1

(c) 12s 

Time period of Oscillation = 2 × (time taken to go from A to B + the next time taken to return at B) 

= 2 × (3 + 3) 

= 2 × 6 

Time period = 12s
