Two circular coils are concentric and lie in the same plane. The inner coil contains 120 turns of wire, has a radius of 0.012 m,

RUDIKE [14]

Answer:

5.152 A

Opposite to the inner coil

Explanation:

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

$I_o$ = Outer coil current

$I_i$ = Inner coil current = 5 A

$N_i$ = Turns in inner coil = 120

$N_o$ = Turns in outer coil = 165

$R_i$ = Inner radius = 0.012 m

$R_o$ = Outer radius = 0.017 m

Putting the magnetic field as equal we have

$\dfrac{\mu_0I_iN_i}{2R_i}=\dfrac{\mu_0I_oN_o}{2R_o}\\\Rightarrow I_o=I_i\dfrac{N_i}{N_o}\dfrac{R_o}{R_i}\\\Rightarrow I_o=5\times \dfrac{120}{165}\times \dfrac{0.017}{0.012}\\\Rightarrow I_o=5.152\ A$

The magnitude of current is 5.152 A,

The direction of the current is opposite to that of the inner coil as they have opposing magnetic fields

The figure shows a water-filled syringe with a 4.0-cm-long needle. What is the gauge pressure of the water at the point P, where

mars1129 [50]

Answer:

Pressure at P point is given as

$P_p = 1.042 \times 10^5 Pa$

Explanation:

As we know by poiseuille's equation of viscous flow of liquid through cylindrical pipe

$Q = \frac{\Delta P \pi r^4}{8\eta L}$

here we know that

L = 4 cm

$\eta = 1 \times 10^{-3} Pa s$

r = 1 mm

Q = flow rate

$\pi r^2 v = \frac{\Delta P \pi r^4}{8\eta L}$

$v = \frac{\Delta P r^2}{8 \eta L}$

$10 = \frac{\Delta P (10^{-3})^2}{8(1 \times 10^[-3})(0.04)}$

$3.2 \times 10^{-3} = \Delta P (10^{-6})$

$\Delta P = 3.2 \times 10^3 Pa$

now we have

$P_p - P_{atm} = 3.2 \times 10^3$

$P_p = 1.01 \times 10^5 + 3.2 \times 10^3$

$P_p = 1.042 \times 10^5 Pa$
