The force of attraction between a -165.0 uc and +115.0 c charge is 6.00 n. what is the separation between these two charges in meter rounded to three decimal places? (k = 1/ 40 = 9.00 x 10°n. m2/c2, 1°c = 10 c)

Explanation:

To obtain the forces between the particles, we can use Coulomb's Law in scalar form, this is, the force between the particles will be:

where k is Coulomb's constant, and are the charges and d is the distance between the charges.

Working a little the equation, we can take:

And this equation will give us the distance between the charges. Taking the values of the problem

(the force has a minus sign, as its attractive)

And this is the distance between the charges.

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.
