The kinetic energy of a charged particle...

The kinetic energy of a charged 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.

Here. Decreases in K.E = work done
= 10J.
`V_(1) = 100` volt, `V_(2) = 200 V, q = ?`
As work done = charge `xx` potential diff.
`:. 10 = q (V_(2) - V_(1)) = q (200 - 100)`
`q = (10)/(100) = 0.1C`
