A-The particle will feel a non-zero net force away from the center point B-The p

Question

A-The particle will feel a non-zero net force away from the center point

B-The particle will feel a non-zero net force towards the center point

C-particle will feel zero net force.

2) A point charge (Charge = 10 mC, Mass = 6 g) is accelerated through a potential difference of 500 Volts. What is the magnitude of the change in kinetic energy of the particle?

= J    

3) A region of space has an electric potential equal to V(x) = 1 x2. What is the magnitude of the electric field at the point x=1?

= N/C    

4) Which of the following statements is NOT true?

A-Electric potential is a vector quantity

B-The electric field points in the direction in which the electric potential decreases most rapidly

C-Electric potential energy is a scalar quantity

D-The SI unit for electric potential is the Volt

E-The electron-volt is a unit of energy

True or False? If the electric potential at a certain point in space is zero, then the electric field at that same point in space is also zero.

True or False

Explanation / Answer

1) C-particle will feel zero net force.

2) change in inetic enrgy = workdone on charged particle

= q*delta V

= 10*10^-3*500

= 5 J

3) E = dV/dx

= 2*x

at x = 1

E = 2*1 = 2 N/c

4)
A -> False
B --> True
C --> True
D--> True

E--> True

lost staement --> False
