1The conductor is neutral (no net charge) When a charged rod is brought close to it (without touching) the net force on the conductor will be
- Aattractive
- Brepulsive
- Czero
- Dit depends on whether the rod is positive or negative
2The tension in each string is

- Amg
- Bmgcos30
- Cmg/cos30
- Dmgtan30
- Enone of the above - it depends on the charge
3what happens to each angle if the charge on the left is doubled, and the other one is halved?

- ABoth increase
- Bboth decrease
- C(theta)1 increases, (theta)2 decreases
- D(theta) 1 decreases, (theta) 2 increases
- Eboth stay the same
4Two small conducting spheres have unequal charges of opposite sign, so that they attract each other with force F(i) when seperated by a distance d. They are brought into contact, and seperated again by the distance d. The force F(f) between the spheres is now
- Azero
- Bsmaller, and still attractive
- Csmaller, but repulsive
- Dlarger, but repulsive
- Enot enough information
5Two charges, q1 and q2, are placed as shown in the figure below. If q1=q2=1.04 uC and d=5m, approximately, what is the magnitude of the total electric field at point P?

- A600 N/C
- B1200 N/C
- C2400 N/C
- DOver 10 000 N/C
6What is the direction of E at point B ?

- A+i (right)
- B-i (left)
- C+j (up)
- D-j (down)
7which way will the dipole start to move in the electric field shown?

- Aup
- Bdown
- Cleft
- Dright
- Enowhere - there is no net force
8Does this dipole feel a torque

- Ayes - clockwise
- Byes - counter clockwise
- Cno
- Ddepends on the strength of E
