Question

Objects 1 and 2

attract each other with
a electrostatic force
of 72.0 units. If the charge of Object
is one-third the
original value AND the charge of object 2 is doubled AND
the distance separating Objects 1 and 2 is doubled, then the
new electrostatic force will be
units.

Answer 1

12 units

Step-by-step explanation:

Original F = C q1q2/r^2 now change the parameters

New F = C 1/3 q1 2 q2 / (2r)^2

= 2/12 C q1q2/r^2 <=======the new force is 1/6 of original

1/6 * 72 = 12 units
