Please answer all parts. Thank you!

PART A)

A pair of electrically charged objects attract each other with a force of 24 N when they are a distance of 2 m apart. If their charges stay the same, then what will be the attractive force between them when they are 8 m apart? Submit Answer Tries 0/2

PART B)

A pair of point charges attract each other through Coulumbs interaction with a force of 2 N when they are placed at a distance of 5 m apart. If the distance remains the same and one of the charges is increased by a factor of 2, then what will be the new attractive force between them? Submit Answer Tries 0/2
