Answer:
(a)
(b) The force is repulsive
Explanation:
a) According to Coulomb's law, the magnitude of the electrice force that one particle exerts on the other is defined as:
Here k is the coulomb constant, and are the signed magnitudes of the charges and d is the distance between them.
b) According to Coulomb's law, if the two charges have the same sign, the electrostatic force between them is repulsive.
Answer:
-67 m/s
Explanation:
We are given that
Mass of ball,m=0.4 kg
Initial speed,u=14 m/s
Impulse,I=-32.4 N-s
Time,t=27 ms=
We have to find the mass's velocity in the x- direction.
We know that
Substitute the values
<span>P1V1/T1=P2V2/T2
isolate V2 and calculate
remember the temperature has to be in Kelvin
K=C+273
the pressure in this case is not necessary to convert to atm you can use the mmHg you will get the same answer</span>
Answer:
-11776.36 N
This force is attractive since both charges are of opposite sign
Explanation:
Given that
Distance between the spheres = 2.73 cm =0.0273 m
where K is Coulomb's constant =
According to coulombs law we know that force between two charges is given by
This force is attractive since both charges are of opposite sign
