PLEASE HELP URGENTLY!!!! WILL AWARD BRAINLIEST!!!

1. An Electric dipole generates an electric field in the space around it. What do all of the electric field lines have in common?

A. All lead from the negative charge to the positive charge

B. All are parallel to the line connecting the two point charges

C. All lead from the positive charge to the negative charge

D. All are perpendicular to the line connecting the two point charges

3. A Van de Graaff generator causes a total charge q to build up on a metal sphere of radius r. Which variable does not affect the electric field at a distance R from the center of the metal sphere? Assume R>r.

A. The distance R from the center of the metal sphere

B. The magnitude of the charge q

C. The radius r of the metal sphere

D. The sign of the charge q

6. A scientist fixes a test charge q^1 to point P and then measures the electrostatic force it experiences there. She then calculates the magnitude of the electric field by applying the equation E=F^1/q^1. Which change to her procedure would vary the value of E that she calculates?

A. keep the test charge in the same location, but alter its charge from q^1 to -q^1

B. keep the charge on the test charge the same, but move the test charge to a different position farther away

C. keep the test charge in the same location, but alter its charge from q^1 to 2q^1

8. A moving electron enters an electric field. The initial velocity of the electron is in the same direction as the electric field. How will the electric field attract the motion of the electron?

A. The electron will accelerate in the opposite direction of its motion

B. The electron will accelerate in the same direction as its motion

C. The electron’s speed will remain constant as it changes direction

D. The electron’s speed will increase as it changes direction

The electric field strength in the space while surrounding a source charge is directly proportional to the quantity of charge and inversely proportional to the distance from the source charge.

Electric field lines is the visual representation of the vector nature of electric field. These lines will always be directed from positive charged source to negative charged source.
