359933 Assertion :
For the planets orbiting around the sun, angular speed, linear speed, \(K.E\) changes with time, but angular momentum remains constant.
Reason :
No torque is acting on the rotating planet. So its angular momentum is constant.

359934 A particle of mass \(m\) is subjected to an attractive central force of magnitude \(\frac{k}{{{r^2}}},k\) being \(\mathrm{a}\) constant. If at instant when the particle is at an extreme position in its closed orbit, at a distance ' \(a\) ' from the centre of force, its speed is \(\sqrt {(k{\rm{/}}2ma)} ,\) if the distance of other extreme position is \(b\). The ratio of \(a / b\) is

359935 The earth moves around the sun in an elliptical orbit (as shown in figure). The ratio \(\frac{{OA}}{{OB}} = x.\) The ratio of the speed of the earth at \(B\) to that at \(A\) is found to be \(x^{N}\). The value of \(N\) is
