A simple pendulum is oscillating without damping. When the displacement of the bob is less than the maximum, its acceleration vector is 
is correctely shown in
is correctely shown inOptions
A.
B.
C.
D.
Solution
Net acceleration
of the bob in position B has two components.(a)
= radial acceleration (towards BA)(b)
= tangential acceleration (perpendicula to BA)Therefore, direction
is correctly shown in option (c).Create a free account to view solution
