Charges of +3 âµc and –5 âµc are 2 mm from each other. the –5 âµc charge is replaced with a +5 âµc charge. how will the electrical force between the charges compare with the original force? a. same force, but in the opposite direction b. same force, but in the same direction c. greater force, but in the opposite direction d. greater force, but in the same direction

a. same force, but in the opposite direction

Explanation:

Charges of +3 µC and –5 µC are 2 mm from each other. The –5 µC charge is replaced with a +5 µC charge. How will the electrical force between the charges compare with the original force? a. same force, but in the opposite direction b. same force, but in the same direction c. greater force, but in the opposite direction d. greater force, but in the same direction

we know from electric force field that the electric force is directly proportional to the product of the two charges and inversely proportional to the square of the distance apart of the two charges

F=k

k=constant

Q and q= are electric charges measured in coulombs

r=distance apart

k(3)(-5)/r^2=k(3)(5)/r^2

the Left hand side is negative while the right hand side is positive

so b holds

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
