two charges q and 2q having masses m and 2m they are allowed to move in uniform electric field at same time. find ratio of their kinetic energies
do you know how to find the force acting on a charge when place in an electric field?

F=qE ma=qE a=qE/m for q1 charge starts with at rest u=0 v1=u+at v1=0+(q1E/m1)t v1=(q1E/m1)t simirarly, for charge q2 v2=(q2E/m2)t according to the quation. K1/K2=1/2
@mahmit2012 i think ur answer is wrong........
no take a look both are the same!! I've just found K2/K1 !!!
ya @mahmit2012 ....u r right
