Question

Two blocks of masses m1 and m2 are in contact lie on a horizontal smooth surface . If two blocks are always in contact , what is the force at their commn interface?

Answer 1

Explanation:

Given Two blocks of masses m1 and m2 are in contact lie on a horizontal smooth surface . If two blocks are always in contact , what is the force at their common interface?

• We need to find the force at the common interface.
• Common interface is one where in both are in contact with each other.
• Both m1 and m2 are kept on a smooth surface. If we apply force then we have maximum acceleration.
• Suppose a force F is applied on m1 then total mass will be m1 + m2.
• So we have a common acceleration a
• So we get F = (m1 + m2)a.
• So a = F / m1 + m2
• Now according to Newton’s third law we have every action has an equal and opposite reaction.
• Also action and reaction are opposite in direction and equal in magnitude.
• Therefore f = m2 a
•          So f = m2 x F / m1 + m2
•       Or f = m2 F / m1 + m2
• So this will be the interface so that the body will be in contact with each other.
