Answer:
F = 309.24 N
Explanation:
Given that,
Charge on a strom cloud, q₁ = 0.055 C
The charge gained by the top of a tree, q₂ = -0.006 C
The cloud moves to 98 meters above the tree.
We need to find the amount of force between the cloud and the tree. The electrical force between two charges is given by :

So, the force between the cloud and the tree is equal to 309.24 N.
Answer:
2.6 kilo Ohm
Explanation:
Capacitance, C = 591 μF = 591 x 10^-6 F
Vo = 88.5 V
V = 11.9 V
t = 3.09 s
Let the resistance is R.



Take natural log on oth the sides
ln 0.135 = - 3.09 / RC
RC = 1.545
R = 1.545 / ( 591 x 10^-6)
R = 2614.2 ohm
R = 2.6 kilo Ohm
Thus the resistance is 2.6 kilo Ohm.
Answer:
F = 180 N
Explanation:
Given that,
Charge, q₁ = 10 μC
Charge, q₂ = 20 μC
The distance between the charges, r = 10 cm = 0.1 m
We need to find the magnitude of the electrostatic force. The formula for the electrostatic force is given by :

So, the magnitude of the electrostatic force is 180 N.
No, magnets can repel against each other and it is still a magnetic force.
