A certain charge Q is divided into two parts q and Q-q which are then seperated by a certain distance.What must q be iin terms of Qto maximise the electrostatics repulsion between the two charges?
explain cyclotron in a more elaborate way
Why does the electric field inside a dielectric decrease when it is placed in an external electric field?
a car moving with a speed of 40km/hr can be stopped by applying brakes after at least 2m.If the same car is moving with 80km/hr.What is the least stopping distance?
a semi infinite line charge of linear charge density 'D' has the shape of an infinitely long straight wire whose one end is connected to three-fourth circle of radius 'R' while one of the diameters of 3/4th circle is parallel to the infinitely long straight part.What is the field at the centre of the circle.How?
