Answer:
The potential energy when it reads 40 N is
Explanation:
From the question we are told that
The lowest reading of the spring balance is 0 N and this is at 0 cm = 0 m
The height reading of the spring balance is 60 N and this is at 20 cm = 0.20 m
Generally the length corresponding to the reading of 40 N is mathematically represented as
=>
Generally the potential energy is mathematically represented as
Here
So
=>
Answer:
Twice the initial value
Explanation:
Let the current be = I
the width of the conducting strips be = a
We know that magnetic field between two plates is given by
If the direction of this magnetic field is same between the two plates, then
= 0
And when the currents runs opposite at each plate, then
Hence the magnetic field will be twice the initial value of the magnetic field that runs between the plates.
