Two shirts are removed from a dryer and attract each other with a force of 0.5n while they are separated by 1 cm. if the two shirts are equally charged, what would their charge and the force be if they are separated by 4 cm?

1) Charge:

Explanation:

The electrostatic force between the two shirts is:

where

k is the Coulomb's constant

q1 = q2 = q is the charge of each shirt (they are equally charged)

r = 4 cm = 0.04 m is the distance between the shirts

F = 0.5 N is the force

Re-arranging the equation, we can find q, the charge of each shirt:

2) Force if they are separated by 4 cm: 0.03 N

In this case, the force between the two shirts would be:

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

it is easily magnetized.
