Question:
Directions : How many minimum number of straight lines are required to draw the problem figure ?
Directions : How many minimum number of straight lines are required to draw the problem figure ?
Show Hint
Count the longest straight lines in the figure; segments lying on the same straight line count as one line.

The Correct Option is A
Solution and Explanation
The figure is made of two overlapping large triangles (a star-like shape) with a few lines inside.
Outer lines: the top horizontal line, the bottom horizontal line, the two slanting sides of the upward triangle and the two slanting sides of the downward triangle. That is 6 lines.
Inner lines: (7) the line from the top apex to the inner point; (8) the horizontal line from the left crossing to the inner point; (9) the long line from the left side of the upper triangle through the inner point to the bottom right corner; (10) the line from the inner point to the top right corner; (11) the short line from the bottom edge up to the right side of the downward triangle.
No two of these segments lie on the same straight line, so they cannot be merged. Total = 6 + 5 = 11.
Answer: (1) 11

- 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:
