A particle a has charge q and particle b

Asked by admin @ in Physics viewed by 324 People

A particle has charge +q and particle b has has charge +4 q with each of them having the same mass m. When allowed to fall from rest through the same electrical potential difference, the ratio of their speeds will become

Answered by admin @


Ka/Kb=q×v/4q×v =1/2mVa^2/1/2mVb^2
Va^2/Vb^2=1/4
Va/VB=1/2
Va:Vb=1:2
It is the ratio between the kinectic energies between the two particles....
Hope this is useful for u guys ....
