Force between the plates of capacitor Introduction Capacitors are fundamental components in electronics, used to store electrical energy. When a voltage is applied across the plates, an electric field develops, causing a charge to accumulate on the plates. The capacitor stores energy in the electric field created between the plates. Among various types of capacitors,

Additional Velocity Required to Overcome Earth’s Gravitational Pull for Satellite Escape Escape velocity is the minimum velocity an object must attain to break free from the gravitational attraction of a massive body without further propulsion. For an object on the surface of the Earth, this velocity is approximately 11.2 kilometers per second (or about 25,000
Kepler’s law of period Kepler’s law of period for planetary motion According to Kepler’s laws of period for planetary motion, the square of the period of revolution of as planet around the sun is directly proportional to the cube of the semi-major axis of its orbit. Mathematically, it can be expressed as , where �T
