Field lines always point away from the positive side of a magnet. So i would say east but im not to sure

Answer from: marygatewell385

Towards East

Explanation:

The direction of the electric force per unit charge i.e. the electric field is given by the direction of motion of positive test charge under the electric force. The field lines are directed radially outwards for a positive charge and radially inwards for a negative charge.

Thus, the electric field points towards East for the position directly east of a positive charge

Answer from: Quest

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 -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [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.
