Answer:

$\dfrac{L_A}{L_B}=16$

Explanation:

$\mu_0$ = Vacuum permeability = $4\pi \times 10^{-7}\ H/m$

n = Number of turns

A = Area

I = Current

Self inductance is given by

$L=\mu_0n^2IA$

Here, A has more turns so the self-inductance of A will be higher

For A

$L_A=\mu_0n_A^2IA=\mu_0(4n_B)^2IA$ $[\because n_A=4n_B]$

For B

$L_B=\mu_0n_B^2IA$

Dividing the above two equations we have

$\dfrac{L_A}{L_B}=\dfrac{\mu_0(4n_B)^2IA}{\mu_0n_B^2IA}\\\Rightarrow \dfrac{L_A}{L_B}=16$

$\therefore \dfrac{L_A}{L_B}=16$

Answer:

6666.67 Newtons

Explanation:

The formula F=ma (force is equal to mass multiplied by acceleration) can be used to calculate the answer to this question.

In this case:

mass= 0.1mg= 1*10^-7 kg
velocity= 4.00*10^3 m/s
time= 6.00*10^-8 s

Using velocity and time, acceleration can be calculated as:

a= 6.667*10^10 m/s²

Substituting these values into the formula F=ma, the answer is:

F= (1*10^-7)kg * (6.667*10^10) m/s²
F= 6666.67 Newtons of force
