Q1. A vertical electric field of magnitude 3.00 multiplied by 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 14.0°. Conclude the electric flux through the bottom of the car.
Q2. Intuitively, the man will not catch the bus unless he is running fast enough. In mathematical terms, there is a constraint on the man's speed so that the equation above gives a solution for that is a real positive number.
Find, the minimum value of for which the man will catch the bus.
