The kinetc energy of a chargd particle decreased by 10 J as it moves from a point at potential 100 V to a point at potential 200V . Find the charge on the particle.

Text Solution

Verified by Experts

Decrease in `KE=` increase in PE
`10J=(200-100)xxq_(0)`
or `100xxq_(0)=10` or `q_(0)=(10)/(100)=0.1C`
