"Speed" is the rate at which distance is being covered .... the ratio
of distance covered to the time it takes.
"Velocity" is the rate at which distance is being covered .... the ratio
of distance covered to the time it takes ... AND the direction in which
it is covered. 'Speed' with the direction of the motion.
Q = magnitude of charge on each of the two point charge = 3.60 mC = 3.60 x 10⁻³ C
r = distance between the two point charges = 9.3 cm = 0.093 m
k = constant = 9 x 10⁹ Nm²/C²
F = magnitude of the force between the two point charges = ?
according to coulomb's law , force between two charges is given as
F = k Q²/r²
inserting the values
F = (9 x 10⁹) (3.60 x 10⁻³)²/(0.093)²
F = 1.35 x 10⁷ N
Answer:
a. FALSE
b.TRUE
C. FALSE
Explanation:
The formula fot the distance between two points is given as
hence we determine the distances between all the points
a.P(3,2,-4), Q(1,0,-4), R(2,1,1)
For point PR
we have
B. For point RP
for point RQ we have
|RP|=|R Q|
C.
For point Q R
