Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

You should try in this way: let's take the origin 'O' at (0,0,0). Position vector of point 'P' will be: OP = 0i + 1j + 1k Similarly, position vector of OQ is: OQ = (π/2) i - 1 j + 2 k so displacement of the particle is: dx = PQ = OQ - OP = (π/2) i - 2 j + 1 k now work done should be dw = f.dx Solve it, you should get the answer.
