There are two balls touching each other circumferencically. The radius of the big ball is
4 times the diameter of the small all. The outer small ball rotates in anticlockwise direction
circumferencically over the bigger one at the rate of 16 rev/sec. The bigger wheel also rotates
anticlockwise at N rev/sec. What is 'N' for the horizontal line from the centre of small wheel
always is horizontal.
help me to solve this
