Answer:

The lines of force run circles around the wire.

Explanation:

The region around a magnetic material or a moving charge particle is called magnetic field. The direction of magnetic field line is given by right hand thumb rule.

The thumb denotes the direction of electric current, then the curled finger will show the direction of magnetic field.

For a straight wire, the direction of magnetic field lines are circular.

Hence, the correct option is (C).

The answer to this is C. The reason being is because if you were to use a compass then it would be making circular motions towards the middle of the wire.

A dipole of moment 0.5 e·nm is placed in a uniform electric field with a magnitude of 8 times 104 N/C. What is the magnitude of
Over [174]

Answer:

The net torque is zero

Explanation:

Let's assume that the dipole is compose of two equal but oposite charges e, and it cam be represented by a rod with one end having a charge e and the other end with a charge of -e. Notice that the dipole is parallel to the electric field thus the force felt by both of the charges will be parallel to the electric field. This means that there will be no components of the forces that are perpendicular to the rod which is a requirement for it to have a torque.

84. Three resitors each of value 30 respectively are connected in a parallel
kati45 [8]

Answer:

each resistor draws 1/3 of an amp or 0.33333 amps

Explanation:

V = I * R

V = 10 volts

R = 30 ohms

10 = I * 30       Divide by 30

10/30 = I

I = 0.33333
