Question

6.	A body has moved from its initial position at origin along X-axis to a final position x=5m under the influence of a force given by F=(4i+2j)N. What is the work done by the force in moving the body from its initial position to its final position horizontally?
A.100J     B.50J       C. 25J      D.  20J

GPT-5 mini · Answer

Work = F · Δr. Displacement = 5i (from 0 to x = 5).  
W = (4i+2j) · (5i+0j) = 4×5 + 2×0 = 20 J.
