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

Options

A.
B.
C.
D.

Answer

C

Explanation

Net acceleration of the bob has two components.
(i) `veca_r` = radial acceleration (ii) `veca_t` = tangential acceleration
Therefore, direction of `veca` is correctly shown in option (c).
