1. What is the magnitude of the force on a charge of +40 μC that is 0.6 m from a charge of - 80 μC?

The magnitude of the force is 79.893 N.

Explanation:

The magnitude of the electrostatic force between the two particles is determined by Coloumb's Law, whose formula is:

(1)

Where:

- Electrostatic constant, in newtons-square meters per square coulomb.

- Electric charges, in coulombs.

- Distance, in meters.

If we know that , , and , then the magnitude of the force is:

The magnitude of the force is 79.893 N.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

the bal will not change its velocity.
