Given:
The charge (q) = 50mc
The speed of the charge is (v) = 50m/s
To find:
The mechanical force acting on the charged particle.
Solution:
As we know, for calculating the mechanical force on a charged particle the formula used is:
F = q ( v x B )
here,
F is the mechanical force,
q is the charge
v is the velocity of the charged particle,
B is the magnetic field.
Now, from the equation, it is clear that velocity and magnetic field have a cross product.
So, the formula becomes
F = qvBsinø
As we know, from the question that the angle between the velocity and magnetic field is zero. As they are parallel to each other. Hence sin0 is also zero.
Therefore, the mechanical force also becomes zero.
