3. Suppose that the strength of electric field about an isolated point charge is 16N/C at a distance of 1 m. What will be the strength of the electric field at
a distance of 2m? Explain your answer. What law guides your answer?

The car would move to the right with 150 n of force. the 150 n of force from friction and air resistance slows the car from moving to the right with 300 n of force.

Then the answer would be d then

When is this
