Laws of Motion

270074 A constant force ( \(\mathbf{F}\) ) is applied on a stationary particle of mass ' \(m\) '. The velocity attained by the particle in a certain interval of time will be proportional to

1 \(m\)
2 \(1 / m\)
3 \(\sqrt{m}\)
4 \(\frac{1}{\sqrt{m}}\)
Laws of Motion

270075 A force produces an acceleration of \(a_{1}\) in a body and the same force produces an acceleration of \(a_{2}\) in another body. If the two bodies are combined and the same force is applied on the combination, the acceleration produced in it is

1 \(a_{1}+a_{2}\)
2 \(\frac{a_{1}+a_{2}}{a_{1} a_{2}}\)
3 \(\frac{a_{1} a_{2}}{a_{1}+a_{2}}\)
4 \(\sqrt{a_{1} a_{2}}\)
Laws of Motion

270076 To keep a particle moving with constant velocity on a frictionless surface, an external force

1 should act continuously
2 should be a variable force
3 not necessary
4 should act opposite to the direction of motion
Laws of Motion

270077 If action force acting on a body is gravitational in nature, then reaction force

1 may be a contact force
2 may be gravitational force
3 may be a gravitational or contact force
4 may be a force of any origin
