An object of mass ' m ' initially at rest on a smooth horizontal surface starts moving under the action of a force F=2 N. In the process of its linear motion, the angle θ (as shown in the figure) between the direction of force and horizontal varies as θ=kx, where k is a constant and x is the distance covered by the object from its initial position. The expression for kinetic energy of the object will be E=nlsinθ. The value of n is 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
