The system is pushed by a force F as shown in figure. All surfaces are smooth except between B and C Friction coefficient between B and C is `mu`. Minimum value of F to prevent blokc B from downward slipping is  img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/MPP_PHY_C04_E01_032_Q01.png" width="80%"
