A uniform force of

\left( {3\hat i + \hat j} \right)

newton acts on a particle of mass 2 kg. The particle is displaced from position

\left( {2\hat i + \hat k} \right)m

to position

\left( {4\hat i + 3\hat j - \hat k} \right)m

. The work done by the force on the particle is

View answer and explanation

Correct option: D

9 J

Option D (9 J) is correct because the work done is the dot product of the force and the displacement vector.

ball is dropped on the ground from a height of

2 {~m}

. If the coefficient of restitution is 0.6 , the height to which the ball will rebound is A running man has the same kinetic energy as that of a boy of half his mass. The man speed up by

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in

\mathrm{\vec F} = - K\left( {y\hat i + x\hat j} \right)

(where K is a positive constant) acts on a particle moving in the x-y plane. Starting from the origin, the particle is taken along the positive x-axis to the point (a,0) and then parallel to the y-axis to the (a,a). The total work done by the force
