Question

What is the relation between velocities of points A and B in the given figure.

  1. negative 2 V subscript A end subscript plus V subscript B end subscript equals 0    
  2. 2 V subscript A end subscript minus V subscript B end subscript equals 0    
  3. 3 V subscript A end subscript minus V subscript B end subscript equals 0    
  4. negative V subscript A end subscript plus V subscript B end subscript equals 1    

The correct answer is: 3 V subscript A end subscript minus V subscript B end subscript equals 0
