According to Newton, the viscous force acting between liquid layers of area A and velocity gradient $ \frac{\Delta \upsilon }{\Delta z} $ is given by $ F=\eta A\frac{\Delta \upsilon }{\Delta z} $ where $ \eta $ is a constant called coefficient of viscosity. The dimension of $ \eta $ are:

The maximum and minimum distance of a comet from the sun are $ 8\times 10^{12}m$ and $ 1.6\times 10^{12}m$ . If its velocity when nearest to the sun is 60 m/s, what will be its velocity in m/s when farthest?
