A force vec F = (3 vec i + 4vec j)N , acts on a particle moving in x-y plane. Starting from origin, the particle first goes along x-axis to thepoint (4,0)m and then parallel to the y -axis to the point(4, 3)m. The total work done by the force on the particle is (##NAR_NEET_PHY_XI_P2_C06_E09_014_Q01.png" width="80%">
