Right option is (a) 0

To explain I would say: Acceleration of the follower is given by the equation:

ω^2(r1+r2)(2-cos^2θ)/cos^3θ

This will occur at θ=0 degrees.

If θ is the angle turned by the cam from the beginning of the roller displacement, then minimum acceleration pf the follower occurs at what value of θ in degrees?
