Question

Objects 1 and 2 attract each other with a electrostatic force of 36.0 units .If the charge of object 1 is doubled AND the charge of object 2 is tripled ,then the new electrostatic force will be __ units

Answer 1

216 units

Step-by-step explanation:

F1 = kQ1Q2/r^2 = 36 (Coulomb's law)

F2 = k(2Q1)(3Q2)/r^2

= 6[kQ1Q2/r^2]

= 6F1

= 6 x 36

= 216 units
