A bob suspended from the ceiling of a car which is accelerating on a horizontal road. The bob stays t rest with respect to the car when the string is making an angle `theta` with the vertical.The linear momentum of the bob as seen from the road is increasing with momentum? If not, where is the external force which changes the linear momentum?
