The given system of equation can be written in the form of AK = B

Now,  = 3 × 1 - 2 × 2 = 3 - 4 = -1 ≠ 0.

∴ The system has unique solⁿ  and hence equation are consistent

mg In equilibrium,  $F_{}=\theta$

$=\theta$

$\theta =\frac{F_{}}{}=\frac{{}^2}{4\pi {\in }_0{}^2\times }$

also $\theta \approx \stackrel{}{?}=\frac{/2}{\mathcal{l}}$

Hence,  $\frac{}{2\mathcal{l}}=\frac{{}^2}{4\pi {\in }_0{}^2\times }$

$\Rightarrow {}^3=\frac{2{}^{2}p}{4\pi {\epsilon }_0}$

$={\left(\frac{{}^2\mathcal{l}}{2\pi {\in }_0}\right)}^{1/3}$

Therefore $\propto {\mathcal{l}}^{1/3}$

Given, A is an invertible matrix of order 2.

∴ Option (B) is correct.

Explanation- power = 1W

Zener breakdown voltage = 5V

Minimum voltage = 3V

Maximum voltage = 7V

Current = power/voltage= 1/5=0.2A

The value of R for safe operation would be R = max voltage – Zener voltage/current

= 7- 5/0.2 = 2/0.2 = 10ohm
