Explanation Introduction: The average force acting on a body during a collision is equal to the rate of change of the momentum of the body. The difference in the final momentum and the initial momentum during the time interval of the collision gives the value of the magnitude of the impact force. Thus, to measure the magnitude of the force, only the parameters related to the momentum and the time are required. The average force is given by F avg = m ( v f − v i ) Δ t Here, m is the mass, v f is the final velocity, v i is the initial velocity, Δ t is the time interval

4.) The diagram shows the electric field lines of a positively charged conducting sphere of radius R and charge Q. A B Points A and B are located on the same field line. A proton is placed at A and released from rest. The magnitude of the work done by the electric field in moving the proton from A to B is 1.7×10-16 J. Point A is at a distance of 5.0×10-2m from the centre of the sphere. Point B is at a distance of 1.0×10-1 m from the centre of the sphere. (a) Explain why the electric potential decreases from A to B. [2] (b) Draw, on the axes, the variation of electric potential V with distance r from the centre of the sphere. R [2] (c(i)) Calculate the electric potential difference between points A and B. [1] (c(ii)) Determine the charge Q of the sphere. [2] (d) The concept of potential is also used in the context of gravitational fields. Suggest why scientists developed a common terminology to describe different types of fields. [1]
