A circular loop of radius `R` is bent along a diameter and given a shape as shown in figure. One of `30, A`   the se micircles (KNM) lies in the xz-plane and the other one (KLM) in the yz-plane with their centres at origin. Current I is flowing through each of the semicircles as shown in figure.    (a) A particle of charge q is released at the origin with a velocity `v =- v_0hati`. Find the instantaneous force `F` on the particle. Assume that space is gravity free. (b) If an external uniform magnetic field `B_0hatj` is applied, determine the force `F_1` and `F_2` on the semicircles `KLM` and `KNM` due to the field and the net force `F` on the loop.
