The potential energy of a particle of mass 5 kg moving in the x-y plane is given by U = (-7x + 24y) Joule, x and y being in metre. Initially at t = 0 the particle is at origin and moving with velocity (2î + 3ĵ) m/s. The magnitude of the force on the particle and the acceleration of the particle are
1
35 N, 7 m/s2
2
30 N, 6 m/s2
3
25 N, 5 m/s2
4
None of these
