two charges of equal magnitude q are held a distance d apart. consider only points on the line passing through both charges.
for parts a through d answer with "midway between charges", "at the points, where the charges are", aor "there are no such points"
a) if the two charges have the same sign, find the location of all points (if there are any) at which the potential (relative to infinity) is zero.
b) if the two charges have the same sign, find the location of all points (if there are any) at which the electric field is zero.
c) if the two charges have opposite signs, find the location of all points (if there are any) at which the potential (relative to infinity) is zero.
d) if the two charges have opposite signs, find the location of all points (if there are any) at which the electric field is zero.

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

it was given as a lesson and guide for prayer.
