Two oppositely charged parallel sheets of charge give rise to a field of 9.00×1011 N/C between them. The sheets are square and h

Maksim231197 [3]

Answer:

$Q = 5.75 C$

Explanation:

As we know that due to a thin sheet electric field at a point near its surface is given as

$E = \frac{\sigma}{2\epsilon_0}$

now we have two sheets of opposite charges so the net electric field is double that of field due to one sheet

so we have

$E_{net} = 2E$

$E_{net} = \frac{\sigma}{\epsilon_0}$

$9.00 \times 10^{11} = \frac{Q}{A\epsilon_0}$

now we have

$Q = 9.00 \times 10^{11}(0.85 \times 0.85)(8.85 \times 10^{-12})$

$Q = 5.75 C$

A solenoid having an inductance of 5.41 μH is connected in series with a 0.949 kΩ resistor. (a) If a 16.0 V battery is connected

vekshin1

Answer:

(A) $9.14\times 10^{-9}sec$

(B) $6.20\times 10^{-3}A$

Explanation:

We have given inductance $L=5.41\mu H=5.41\times 10^{-6}H$

Resistance $R=0.949kohm=0.949\times 10^3ohm$

Time constant of RL circuit is equal to $\tau =\frac{L}{R}$

$\tau =\frac{5.41\times 10^{-6}}{0.949\times 10^3}=5.70\times 10^{-9}sec$

Battery voltage e = 16 volt

(a) It is given current becomes 79.9% of its final value

Current in RL circuit is given by

$i=i_0(1-e^{\frac{-t}{\tau }})$

According to question

$0.799i_0=i_0(1-e^{\frac{-t}{\tau }})$

$e^{\frac{-t}{\tau }}=0.201$

${\frac{-t}{\tau }}=ln0.201$

${\frac{-t}{5.7\times 10^{-9} }}=-1.6044$

$t=9.14\times 10^{-9}sec$

(b) Current at $t=\tau sec$

$i=i_0(1-e^{\frac{-t}{\tau }})$

$i=\frac{16}{0.949\times 10^3}(1-e^{\frac{-\tau }{\tau }})$

$i=6.20\times 10^{-3}A$
