Question

A vertical electric field of magnitude 2.50 kN/C exists above the Earth’s surface on a day when a thunderstorm is brewing. A car with a rectangular size of approximately 6.20 m by 3.40 m is traveling along a roadway sloping downward at 12.0˚. Determine the electric flux through the bottom of the car.

Answer 1

vertical electric field : E = 2.5KNIC = 2.5x103 NIC of rectangular cam = (6.2 x 3.4) m² E È Area ( CA) que se 11204 angle So, flux between Ê and Å : 0= 12° through bottom of car: - $ - Ë Ã - EA COMCO) 4 = 2.5 x10° x 6.2 x 3.4 (Nm2) x cos(12) $ = 5.15 x109 Nm2 Answer
