In the given figure, how many squares are present ?
In the given figure, how many squares are present ?
Show Hint
Count the single unit squares first, then count the larger squares (2 by 2 and 3 by 3) that can be formed from them.

The Correct Option is D
Solution and Explanation
The figure is a cross-like arrangement of unit squares with rows of 1, 3, 5, 3 and 1 squares from top to bottom.
Unit squares: 1 + 3 + 5 + 3 + 1 = 13.
Squares of side 2 units: they can only be formed inside the central 3 by 3 block of squares, giving 2 x 2 = 4 such squares.
Squares of side 3 units: the central 3 by 3 block itself gives 1 square.
No 4 by 4 or larger square exists because the outer rows have only 1 square.
Total = 13 + 4 + 1 = 18.
Answer: (4) 18

- 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:
