PHXI06:WORK ENERGY AND POWER

355796 A uniform force of \((3\hat i + \hat j)N\) acts on a particle of mass 2 \(kg\). Hence, the particle is displaced from position \((2\hat i + \hat k)m\) to position \((4\hat i + 3\hat j - \hat k)m\). The work done by the force on the particle is

1 9 \(J\)
2 6 \(J\)
3 15 \(J\)
4 13 \(J\)
PHXI06:WORK ENERGY AND POWER

PHXI06:WORK ENERGY AND POWER

355798 A force \(5 \hat{i}+3 \hat{j}\) newton is applied over a particle which displaces it from its origin to the point \(2 \hat{i}-\hat{j}\) metre. The work done on the particle is

1 +13 joules
2 -7 joules
3 +11 joules
4 +7 joules
