Q1. A vertical electric field of magnitude 3.00 104 N/C exists above the Earth's surface on a day when a thunderstorm is brewing. A car with a rectangular size of 6.00 m by 3.00 m is travelling along a dry gravel roadway sloping downward at 15.0°. Find out the electric flux through the bottom of the car.
Q2. A block of weight W can slide on a horizontal surface. A force of W/n1 is applied to the right that causes the block to accelerate with acceleration equal to g/n2. g is the acceleration by reason of gravity. If the coefficient of kinetic friction is &mu = 1/n3, then what is n3
