A force of

10\hat i - 3\hat j + 6\hat k

N acts on a body of mass 100 g and displaces it from

6\hat i + 5\hat j - 3\hat k

m to

10\hat i - 2\hat j + 7\hat k

m. The work done is

View answer and explanation

Correct option: B

121 J

Option B (121 J) is correct because the work done is the dot product of the force and displacement vectors.

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
