work done by external agent to move a negatively charged particleof mass 2mg from rest away from a fixed positive charge from point p to q is 5mJ,potential energy of the system increases by 4mJ in the process.find the speed of the particle at point q

Expert Answer
potential energy stored, V = 4mJ
total energy = 5mJ = V + K
K = kinetic energy = E - V = 1mJ
let veelocity be v
thus K = 1/2mv2
thus we can calculate v
