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:

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)
