Reference no: EM138538

Q1. If you place a 0.0001-C charge halfway between the terminals of a common 9-v battery, 5 mm apart, what force will that charge experience?

Q2. An airtight box has a removable lid of area 1.7 x 10-2m2 and negligible weight. The box is taken up a mountain where the air pressure outside the box is 0.75 x 10^5Pa. The inside of the box is completely evacuated. What is the magnitude of force necessary to pull the lid off the box?
