In which direction does the electric field point at a position directly west of a negative charge?
A. North
B. West
O C. East
O D. South

East

Explanation:

Electric fields point in the direction of decreasing potential. If there is only one negative charge, the most negative spot would be directly where the charge is. If we measure the electric field to its west, the field would be pointing to the charge, which is to that point's east.

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.
