Two blocks A and B having masses 5 kg and 10 kg respectively are placed one over other on a smooth horizontal surface as shown in the diagram. The coefficient of friction between the blocks is 0.2. The maximum force that should be applied on upper block so that there is no relative motion between the blocks will be; (g = 10 m/s²)

20 N
B
15 N
C
