A partical of M mass and Q charge is thrown to such a area where same gravitational and electric field are situated. What is the way of this partical?

a electron of mass M in rest in initial position.electron walk a certain distance in any electric field in time T1.a proton mass of W in rest in initial position.like the electron proton also walk a same distance in same electric field in time T2.if there is no any gravitational effect then what will be the value of T2/T1?

two infinity linear charges are kept parallel 0.1 meter one another.if every charges included charge of 5 micro columbe per meter,then what will be the value of force on unit length of the linear charges?

four charges are situated in the corner of a square ABCD if a charge q is kept in the center of this square , then what will be the force on charge q?

distance between the two point charges +9e and +e is 16 centimeter.where we can keep a third charge q between them so that they will be in equilibrium?

A 20.0 m long wire is carrying a 150.0 mA current parallel to a second wire that is extremely long which carries a current of 250.0 mA in the same direction. These wires are placed 40.0 cm apart in a 5.5 T magnetic field that is directed into the page. Calculate the magnetic force on each wire and indicate the direction of the force. Each of these wires would generate a smaller magnetic field, indicate the direction this magnetic field would travel between the wires.

At a point that is 3 meters away from a 3 -coloumb point charge, the electric field intensity in N/coloumb, that the charge produces is equal to?

From the analysis of an RLC circuit we can determine the behavior of RL circuit (no capacitor) by putting C = ∞ ,whereas we put L = 0 to determine the behavior of RC circuit (no inductor) .Explain this difference.

A 10,000-watt radio station transmits at 535 kHz.

Calculate the energy of a single photon at the transmitted frequency.

Two electrons (each of charge = e and mass = m) are attached one at each end of a light rigid rod of length 2r. The rod is rotated at constant angular speed about a perpendicular axis passing through its centre. The ratio of angular momentum about the axis of rotation to the magnetic dipole moment of the system is
