Question

A simple pendulum is oscillating without damiping, When the displacement of the bob is less than maximum, its acceleration vector `veca` is correctly show in:
A.
B.
C.
D.

Answer 1

Correct Answer - C
When the displacement of bob is less than maximum, there will be two component accelerations `vec(a)_(T)` and `vec(a)_(C)` of the bob as shown in figure, . Their resultant acceleration `vec(a)` will be represented by the diagonal of the parallelogra. Hence, option (c) is true.
