Condition for the maximum value of mass of block B so that two blocks do not move is given. Calculate the maximum mass mB.

1. mB = 0.2 kg
2. mB = 0.4 kg
3. mB = 0.6 kg
4. mB = 0.8 kg

Correct answer: mB = 0.4 kg

Solution

The maximum mass of block B is determined by balancing the forces acting on the system, considering static friction and gravitational force. Without additional details like coefficients of friction or the setup, the most reasonable answer is mB = 0.4 kg.
