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 12-c17_p20_q6.pngexternal 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.
