A 100−kg man is skiing across the level ground at a speed of 8.0m/s when he comes to the small slope 1.8 m higher than the ground level

A6.0-μf air-filled capacitor is connected across a 100-v voltage source. after the source fully charges the capacitor, the capacitor is immersed in transformer oil (of dielectric constant 4.5). how much additional charge flows from the voltage source, which remained connected during the process?
