5. A current flows in a wire in direction 3i+4j where the direction of the magnetic field is 5i+12k. The direction of force on the wire is?
6. A current I flows in a straight wire of length L at an angle of 30 degrees from the direction of a magnetic field B. the force on this wire is?
7. If the voltage on a capacitor is doubled, then the energy (Efinal) stored by the capacitor is _____ times the initial value (Eintial).

Solution Summary

It finds the force exerted on the current carrying wire by the magnetic field. It also finds the energy stored by the capacitor when the voltage is doubled. The solution is detailed and well presented.
