Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

7. A point charge Q creates an electric potential of 125V at a distance of 15 cm. What is the
value of Q?
8. A 35µC point charge is placed 32 cm from an identical 35µC charge. How much work
would be required to move a 0.50µC test charge from a point midway between them to a
point 12 cm closer to either of the charges?
