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

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
There are two acceleration acting on the body

(i) Centripetal acceleration `vec a_(c)`
(iii) Tangential acceleration `vec a_(t)`
The reulting of these is `vec a = vec a_(t) + vec a_(c)`
its direction is shown in figure.
