Question 7
Figure shows an oscillating pendulum.
Time taken by the bob to move from A to C is t1 and from C to O is t2 . The time period of this simple pendulum is
(a) (t1+t2)
(b) 2(t1+t2)
(c) 3(t1+t2)
(d) 4(t1+t2)
A to O is equal to the 14 th of the oscillation. Hence, time period = 4 times (A to C + C to O) = 4(t1+t2)
