363240 A train is moving with a speed of \(12\;m{\rm{/}}s\) on rails which are \(1.5\;m\) apart. To negotiate a curve of radius \(400\;m\), the height by which the outer rail should be raised with respect to the inner rail is

1 \(6.0\;cm\)
2 \(4.2\;cm\)
3 \(5.4\;cm\)
4 \(4.8\;cm\)

363241 A child of mass \(5\;kg\) is going round a merry go-round that makes 1 rotation in \(3.14\;s.\) The radius of the merry go-round is \(2\;m\). The centrifugal force on the child will be

1 \(50\;N\)
2 \(80\;N\)
3 \(40\;N\)
4 \(100\;N\)
PHXI05:LAWS OF MOTION

363242 The outer rail of the curve railway track is raised above the inner one:

1 To provide centripetal force
2 To overcome the frictional force
3 To balance the gravity
4 For some reason other than those mentioned above

363243 A car moving on a horizontal road may be thrown out of the road in taking a turn:

1 By the gravitational force
2 Due to the lack of proper centripetal force
3 Due to the rolling frictional force between the type and road
4 Due to the reaction of the ground
