Explanation:
By Hooke's Law, Fe = kx.
Since Fe = 1.6N and x = 9.2cm - 8cm = 1.2cm,
k = Fe/x = 1.6N/1.2cm = 1.33N/cm.
Answer:
Explanation:
When a charged particle is moving in a straight line, means undeflected in a crossed magnetic and electric field, it means the net force on the charged particle is zero.
magnetic force is balanced by the electric force
q v B = q E
Where, q be the charge on the particle, v be the velocity, B be the strength of magnetic field, e be the strength of electric field.
So, B = E / v
