A particle of mass m is driven by a machine that delivers a constant power k watts. If the particle starts from rest the force on the particle at time t is A particle of mass m is driven by a machine that delivers a constant power k watts. If the particle starts from rest the force on the particle at time t is August 28, 2020 Category: Chapter 7 - Work, Energy and Power , NEET Last 32 Years Solved 1988 - 2019 Physics and Chemistry Video Solutions , Physics , Facebook Messenger WhatsApp Share this:TwitterFacebook Related Consider a drop of rain water having mass 1 g falling from a height of 1 km. It hits the ground with a speed of 50 m/s. Take 'g' constant with a value 10 m/s^2. The work done by the (i) gravitational force the (ii) resistive force of airs is:A particle of mass m moves along a circular path of radius r with a centripetal acceleration an changing with time t as an=kt2, where k is a positive constant. The average power developed by all the forces acting on the particle during the first t0 seconds is.An α-particle of mass 6.4×10^−27 kg and charge 3.2×10^−19C is situated in a uniform electric field of 1.6×10^5Vm^−1. The velocity of the particle at the end of 2×10^−2m path when it starts from rest is
