Two blocks of masses m_(1) and m_(2) are kept touching each other on a rough fixed inclined plane of inclinationalpha. Coefficients of kinetic friction between the inclined plane and the block m_(1) is k_(1)and between the inclinedplane and block m_(2) is k_(2). Find the force ofinteraction between the blocks in the process of motion. |
