ENGINEERING APPLICATION A small private plane approaching an airport is flying at an altitude of above sea level. As a flight controller at the airport, you know your system uses a vertical electric dipole antenna to transmit at What is the intensity of the signal at the planes receiving antenna when the plane is 4.00 km from the airport? Assume the airport is at sea level.
Physics 2 for Engineering Week 4 Notes 26 September – 29 September Chapter 23 Electric potential energy is a scalar quantity Unit is Joules (J) Potential energy for two point charges assuming U = 0 waen r = infinaty U = kQq / r Review: F = kQq / r 2 E = kq / r 2 Electric potential is a scalar quantity Unit of electric potential is volts (V) 1 V = 1 J / C Unit of electric field is N / C or V / m Assume V = 0 when r = inainity V = kq / r ΔV = E * d at constant electric field For collection of point charges V = Σ kQ / r E direction points from positive charge to negative charge Positive charge moves in the direction of E from high to lo
