A body of mass \(20 \mathrm{~kg}\) is moving on a rough horizontal plane. A block of mass \(3 \mathrm{~kg}\) is connected to the \(20 \mathrm{~kg}\) mass by a string of negligible mass through a smooth pulley as shown in the below figure. The tension in the string is \(27 \mathrm{~N}\). The coefficient of kinetic friction between the heavier mass and the swrface is \(\left(g=10 \mathrm{~m} / \mathrm{s}^2\right.\) )
- A 0.025
- B 0.035
- C 0.35
