A marine cartilaginous fish that can produce electric current is
A system consists of three masses \(m_1\), \(m_2\) and \(m_3\) connected by a string passing over a pulley \(P\). The mass \(m_1\) hangs freely and \(m_2\) and \(m_3\) are on a rough horizontal table (the coefficient of friction = \(\mu\)). The pulley is frictionless and of negligible mass. The downward acceleration of mass \(m_1\) is (Assume \(m_1 = m_2 = m_3 = m\))
Pulley
