Average speed is the answer
The electrostatic force between two charges q1 and q2 is given by

where

is the Coulomb's constant

is the distance between the two charges.
In our problem, the two charges are two electrons, so their charges are equal and equal to

By substituting these values, we find the intensity of the force between the two electrons:

This is the magnitude of the force each electron exerts to the other one. The direction is given by the sign of the charges: since the two electrons have same charge, they repel each other, so the force exerted by electron 1 is toward electron 2 and viceversa.

Explanation:
Given;
mass of the exoplanet, 
radius of the exoplanet, 
The acceleration due to gravity of the planet is calculated as;

Therefore, the correct option is b. 48.0 g
Answer:
Sun light takes 8.5 minutes to reach Earth.
Explanation:
Light travels in vacuum at constant speed
, so we can find the time it takes to travel the given distance from Earth to Sun using a kinematic equation.
Finding the time it takes for Sun light to reach us.
Using the kinematic equation
, we can solve for time t, which will give us

We can replace the equation with the given values, but before doing that, we need the values to be on SI units, thus the distance becomes

Replacing the values on the time equation give us

We get as result 510 seconds, then we must convert them in minutes.

So we can conclude that Sun light takes 8.5 minutes to reach Earth.
