why the electrons collect at the top of the edge of the slice that related to the attraction upward,V and B?
What is the resistance of a 25.0-m-long piece of 12-gauge copper wire having a 2.053-mm diameter?
A race car is about to pass a curve road with a diameter of 450m at a constant speed of 22.5m/s. What is the centripetal acceleration of the race car?
A positive charge Q=8 mC is placed inside the cavity of a neutral spherical conducting shell with an inner radius a and an outer radius b. Find the charges induced at the inner and outer surfaces of the shell.
FIGURE 1 shows two long parallel wires 2 cm apart. Wire P carries a current 7 A to
the right. Point C is 3 cm from wire Q and in the same plane as wire P and Q.
Determine the magnitude and direction of current in wire Q so that the magnetic field
at C is zero.
