NEETPhysicsWork Energy and PowerMCQ+4 / −1
A uniform force of (3i^+j^)\left( {3\widehat i + \widehat j} \right)(3i+j​) newton acts on a particle of mass 2 kg. Hence the particle is displaced from position (2i^+k^)\left( {2\widehat i + \widehat k} \right)(2i+k) metre to position (4i^+3j^−k^)\left( {4\widehat i + 3\widehat j - \widehat k} \right)(4i+3j​−k) metre. The work done by the force on the particle is
  1. A
