QUESTION 1 A negatively charged object has excess a. Electrons O b. Protons O c. Neutrons d. All of these O e. None of these QUESTION 2 What kind of force would you expect to see, if a positively charged plastic rod is brought close to a suspended neutral rod? O a. attractive O b. repulsive O c. no force O d. Depends on the magnitude of the charge O e. there is no way to say QUESTION 3 What kind of force would you expect to see, if the rods of the previous question momentarily touch each other? O a. attractive O b. repulsive O c. no force O d. Depends on the magnitude of the charge O e there is no way to tell

Explanation / Answer

1)

a) electrons

As electrons are the elementary particles carrying negative charge, so they need to be in excess to be negatively charged.

2)

a) attractive

It will induce negatively charge ont he side nearer to the charged plastic

3)

b) Repulsive

Positive Charges will flow to the rod and thus both will repel each other

4)

d) None of the above

5)

d) There is no way to tell.

IF A is +ve, B is -ve , C is -ve and D is -ve, then A will attract C and D

IF A is +ve, B is -ve , C is +ve and D is +ve, then A will repel C and D

So, there is no paticular way to tell .

6)

b) repel each other.

A and B are unlike and C is unlike A So, C and B are like charges.

7)

a) there are more charges present

8)

b) Inversely,

9)

a) At least one of them to be charged
