A system of two blocks connected by a string over an ideal pulley.
A system of two blocks connected by a string over an ideal pulley.
A block of mass \(m\) and a block of mass \(3m\) are connected by an ideal string passing over a frictionless pulley of negligible mass. Initially, the block of mass \(3m\) is held in place by a student so that the system is at rest. The student then releases the block, allowing the system to accelerate. How does the tension in the string change after the block of mass \(3m\) is released?
