Answer:
1.
2.
Explanation:
1. Electrostatic force is given as:
where k = Coulombs constant
q = charge of first charge
Q = charge of the second charge
r = distance between them
From the question:
F = 100 N
q =
r = 0.01 m
We need to find Q.
From the formula of force, we have that Q is:
This is the charge, Q, of the second charge.
2. From the question:
F = 2 N
q =
r =
We need to find Q.
Using the same formula for Q as in 1. above, we have that:
This is the charge, Q, of the second charge.
Answer:
The power dissipated in either one of the parallel resistors is 2 V
Explanation:
Given;
two parallel resistors, R₁ and R₂ = 2 ohms
The total resistance of the Two resistors of 2 ohms connected in parallel is;
when connected to another resistor of 1 ohm in series, the total resistance becomes;
Rt = R₁ + R₂
Rt = 1 + 1 = 2 ohms
Current in the circuit, I = voltage / total resistance
= 2 /2 = 1 A
the overall circuit has been resolved to series connection, and current flow in series circuit is constant.
Power = I²R
Thus, power dissipated in either one of the parallel 2 ohms resistors is;
Power = I²R = (1)² x 2 = 2 V
