If the size of the charge value is tripled for both of twopoint charges maintained at a constant separation, the mutual forcebetween them will be changed by what factor?
a. 9.0
b. 3.0
c. 0.33
d. 1/9
e. 6.0

a) 9.0

Explanation:

The force between two point charges, obeys Coulomb's Law, which can be written as follows:

As it  can be seen, if the separation between the charges remains the same, the new value of the force will be directly proportional to the product of the charges.

If both charges are tripled, the mutual force between them will be changed in a factor equal to 3.0*3.0 = 9.0

explanation:

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
