Question

25. If a force (3i+2j+4k ) newton displaces a particle through a distance (5i+ 3j+2 k) metre,
then calculate the work done by the force on the particle​

Answer 1

Answer:  Explanation: Work done = force × distance So by formula   Work done =(3i+2j+4k)×(5i+3j+2k)                                                      =(3×5i) + (2×3j) + (4×2k)                                          =15i + 6j + 8k  I HOPE IT IS HELPFULL
