Answer:
Explanation:
Let magnetic force F acts towards right and the string makes an angle of θ with the vertical in equilibrium .Let T be tension in equilibrium
T cos θ = mg
T sin θ = F
Dividing
Tan θ = F / mg
F = mg Tanθ
= 51.5 x 9.8 x 10⁻³ x 26 / 20.8 Tanθ = 26 / 20.8 )
= 630.875 X 10⁻³ N

Put the value of R
We need to calculate the drift velocity
Using formula of drift velocity
Put the value into the formula
We need to calculate the time
Using formula of time
Put the value into the formula
Hence, The time is 0.46 sec.
