(The figure shows a carbon resistor whose bands are marked G, O, Y and Golden.)
Show Hint
Read the bands: first two bands give digits, the third is the power-of-ten multiplier, the last is tolerance (gold = 5%).

- \(530\ \mathrm{k\Omega} \pm 5\%\)
- \(5.3\ \mathrm{M\Omega} \pm 5\%\)
- \(6.4\ \mathrm{M\Omega} \pm 5\%\)
- \(64\ \mathrm{k\Omega} \pm 10\%\)

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Colour code: Green = 5, Orange = 3, Yellow = 4 (as multiplier \(10^4\)), Golden = tolerance \(\pm 5\%\).
Resistance = \(53 \times 10^{4}\ \Omega = 530\ \mathrm{k\Omega}\), with tolerance \(\pm 5\%\).
Answer: (1) \(530\ \mathrm{k\Omega} \pm 5\%\)

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
