Answer:
Explanation:
Given that, current generated from lightning range from
10⁴ A < I < 10^5 A
We know that,
The magnetic force is given as
F = iLB
The magnetic field on the earth surface is
B = 10^-5 T
So, let assume the worst case of a 15m flag pole
L = 15m
Then,
F = iLB
F = 10^5 × 10 × 10^-5
F = 15 N
Therefore, 15N is fairly strong so it will come to the material that was use for the material of the flag pole.
Therefore, it is possible that the student is right depending on the material of the flag pole.
Answer:Yes
Explanation:
Yes, there will be a force of gravity acting on the Pencil but it will hover in front of the person because lift would itself having free fall.
Free is the state of body where gravity is the only force acting on the body while it is falling from a height.
According to the theory of relativity, a body under free fall has no force acting on it.
Anything inside the lift will be experiencing the free fall as they are falling under the influence of gravity completely.
