Suppose that you start with a charge of 0.002 C, and find that it takes 24 J of work to move it from point A to point B. Now what is the voltage difference between points A and B?
If this charge is release, what will be its kinetic energy as it flies back past point A?

a) Potential difference is work done the charge against the field. We have
PD=W/q= 24 /.002=12000 V
b)Ke =Pe= 24J

the link u gave is inaccessible. yet in case if the plenty are the two hung by utilising an identical pulley then use following formula: a=(m1-m2)g/m1+m2 and if one is mendacity horizontally on a floor and diverse is surprising then, a=m1g/m1+m2
