An electron is moving with the velocity of `10^(7)m/s`, parallel to a straight wire, carrying a current of 10 A. What is the force acting on the electron, if the electron is at a distance of 4 cm from the wire ?

An electron is moving with velocity vecv along the axis of a long straight solenoid carrying current 'I'. What will be the force acting on the electron due to the magnetic field of the solenoid?

An electron is moving northwards with a velocity 10^(7)m/s in a magnetic field of 3 T directed eastwards. Calculate the instantaneous force on the electron.

If the radius of a wire carrying current is doubled, the drift velocity of the electrons will be :

Two long and parallel straight wires A and B carrying currents of 10.0 A and 4.0 A in the same direction are separated by a distance of 4.0 cm. Estimate the force on a 10 cm section of wire A.

An infinitely long straight consuctor carries a current of 5A as shown. An electron is moving with a speed of 10^5 m/s parallel to the conductor. The perpendicular distance between the electron and the conductor is 20cm at an instant. Calculate the magnitude of the force experienced by the electron at that instant.

Two long and parallel straight wires A and B carrying currents of 0.8 A and 5.0 A in the same direction are separated by distance of 0.4 cm. What is the force on a 10 cm section of wire A ?

Two long and parallel straight wires A and B carrying currents of 8.0 A and 5.0 A in the same direction are seperated by a distance of 4.0 cm . Estimate the force on a 10 cm section of wire A.
