A particle with a charge of +4.30 nC is in a uniform electric field E⃗ directed to the negative x direction. It is released from rest, and after it has moved 8.00 cm , its kinetic energy is found to be 1.50×10−6 J .
A. What work was done by the electric force?
Express your answer in joules to three significant figures.
B. What was the change in electric potential over the distance that the charge moved?
Express your answer in volts to three significant figures.
C. What is the magnitude of E⃗ ?
Express your answer in volts per meter to three significant figures.
D. What was the change in potential energy of the charge?
Express your answer in volts per meter to three significant figures.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
