A point object of mass 2 kg is moved from point A to point B very slowly on a curved path by applying a tangential force on a curved path as shown in figure. Then find the work done (in J) by
external force in moving the body. Given that
Answer:
400
Solution:
Moved very slowly, so kinetic energy change is zero.
External force works against gravity; friction cancels through the slow constraint.
Net work = potential energy gain: J. Answer: 400.
