Question

1)  Two small, identical objects have charges of 6 μC and -3 μC. If the objects are 13 cm apart, what is the electric force the objects exert on each other? (in N)

- 7.99x10^5

- 9.59

- 4.79

- 1.20

- 3.20x10^6

2) Now imagine that the two small, identical objects with charges of 6 μC (Object A) and -3 μC (Object B) are CONDUCTORS. If the objects are brought together so they touch, then separated, what is the amount of charge on each object?

-  Object A has 3.00 μC, Object B has 3.00 μC

-  Object A has 6.00 μC, Object B has -3.00 μC

-  Object A has 1.50 μC, Object B has 1.50 μC

-  Object A has 3.00 μC, Object B has 0 μC

-  Object A has -3.00 μC, Object B has 6.00 μC

3) Two small, identical conductors have charges of 6 μC and -3 μC. If the objects are brought together so they touch, then separated so they are 13 cm apart, what is the electric force the conductors exert on each other? (in N)

- 9.59

- 1.20

- 7.99x10^5

- 3.20x10^6

-4.79

Answer 1

1)

Given:

Charge 1,

Charge 2,

Separation,

Electric force,

ANSWER:Option 2) 9.59N

========================

2)

Initially, charges on object A and Object B are:

When the charged objects touch, the charges will equalize.

Let be the charge on object A and object B after both objects are separated

So

ANSWER: Option 3) Object A has 1.50 μC, Object B has 1.50 μC

=======================================================

3)

Charge 1,

Charge 2,

Separation,

Electric force,

ANSWER:Option 2) 1.20N
