2 answers:
Answer : The correct option is, directly proportional to mass and velocity.
Explanation:
Kinetic energy : It is associated with the state of motion of an object.
The formula used for kinetic energy is,
where,
m = mass of an object
v = velocity or speed of an object
From the formula of kinetic energy we conclude that,
The kinetic energy is directly proportional to the mass and the velocity of an object.
Hence, the kinetic energy is directly proportional to mass and velocity.

To develop this problem we will apply the concepts related to the Electromagnetic Force. The magnetic force can be defined as the product between the free space constant, the current (of each cable) and the length of these, on the perimeter of the cross section, in this case circular. Mathematically it can be expressed as,
Here,
= Permeability free space
I = Current
L = Length
d= Distance between them
Our values are,
Rearranging the previous equation to find the current,
Therefore the current in the rods is 210.6A
