Answer 1

Answer:

$\boxed{Q=(1.385 X 10^{-2})C}$

Explanation:

Torque experienced by dipole (τ) = P X E

                                                        = P·E·Sin(θ) where θ: angle between P and E

∴ τ = (P)($10^5$)sin(60°)

$=> 8\sqrt{3}=(P)10^5(\frac{1}{2})$

$=> P=16\sqrt{3} X 10^{-5}$

Since P= length of dipole X charge;

Charge= P/length of dipole

$=> Q=\frac{16\sqrt{3} X 10^{-5}}{2X10^{-2}} \\\\=>Q=8\sqrt{3} X 10^{-3}$

∴ $\boxed{Q=(1.385 X 10^{-2})C}$

hope this answer helped you :)

Answer 2

Answer:

Answer: The new resistance will be 4 ohm

Ground or Earth

A ground symbol (IEC symbol 5017) identifies a ground terminal. It can be used for a zero potential reference point from where current is measured. It is also for electrical shock protection.
