Two masses each equal to m are lying on x-axis at (-a, 0) and (+ a, 0) respectively. They are connected by a light string. A force F is applied at the origin along y axis resulting into motion of masses towards each other. The acceleration of each mass when position of masses at any instant becomes (- x, 0) and (+ x, 0) is given by
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Let F be applied at origin from figure
F = 2T cos θ θ
or T = F/2cos θ θ
Then force causing motion is given by T
T sin θ θ = 
= 
∴ ∴ acceleration =
