If an object moved in the same direction and at a constant speed for 4 hours, which of the following is true?
a. the object's speed changed during the 4 hours
b. the object; s velocity did not change
c. the object accelerated during the 4 hours
d. the object decelerated during the 4 hours

Iwannasay c is the most accurate

Work is reduced while time is decreased

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
