Problem

A pendulum bob of mass mm is suspended by a light inextensible string of length LL . A constant horizontal force FF is applied to the bob, starting from its lowest vertical position. What is the horizontal component of the displacement of the bob when the string makes an angle θ\theta with the downward vertical? (A) L(1−cos⁡θ)L(1 - \cos \theta) (B) Lsin⁡θL \sin \theta (C) Ltan⁡θL \tan \theta (D) Lcos⁡θL \cos \theta
