When the bob is at maximum displacement its velocity is zero. Hence, centripetal acceleration ac=(v2/R)=0, Therefore, only tangential acceleration will act.

Q. A simple pendulum is oscillating. When the displacements of the bob are maximum, its acceleration vector $a \to$ is correctly shown in :

When the bob is at maximum displacement its velocity is zero.
Hence, centripetal acceleration $a_{c} = \frac{v ^{2}}{R} = 0,$
Therefore, only tangential acceleration will act.

Q. A simple pendulum is oscillating. When the displacements of the bob are maximum, its acceleration vector a→ is correctly shown in :

When the bob is at maximum displacement its velocity is zero. Hence, centripetal acceleration ac​=Rv2​=0, Therefore, only tangential acceleration will act.
