Part find the factor by which the electrostatic force will be multiplied if the indicated changes are made. use formula f= k |q1| |q2| / r^2

Since the force is proportional to the product of charges, the increase by 25% will increase the force by 25%, decreasing the other by 25% will decrease the force by 25%.
The force is inversely proportional to the square of the distance.  So decreasing the distance by 20%  (Factor of 0.2)  increases the force by a factor of
(1/0.8)² = 1.5625

She sold 135 peaches, because if you multiply 2.50 eith 135, you'd get 337.5, the 0 can be added or not.

Your answer is 32 hope i
