Two charges that are both 5 C push each other apart with a force of 762,149 N. How far apart are the two charges?

543.04 m

Explanation:

The 2 charges are:

q1 = q2 = 5 C

Distance apart is r

Force; F = 762149 N

We will use the formula from coulumbs law;

F = kq1•q2/r²

Where k is coulumbs constant = 8.99 × 10^(9) N.m²/C²

Making r the subject, we have:

r = √((8.99 × 10^(9) × 5 × 5)/762149)

r ≈ 543.04 m

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
