Question:
Question figure shows top view/ plan of an object. Identify the INCORRECT 3D view from the given answers figure.
Question figure shows top view/ plan of an object. Identify the INCORRECT 3D view from the given answers figure.
Show Hint
The plan is a square inside a square, so a correct object shows just one square feature on a single plain outer surface when seen from above.

The Correct Option is D
Solution and Explanation
The plan shows an outer square and one smaller inner square at the centre. So seen from above the object must look like a plain outer surface carrying exactly one square feature (a pit or a raised block) with nothing else.
Option (1): a sloping surface with a square pit - from above this gives a square inside a square. Correct.
Option (2): a sloping surface with a raised rectangular block - from above this also gives a square within a square. Correct.
Option (3): a curved top surface with a square-shaped cut-out - from above again a square within a square. Correct.
Option (4): a flat slab carrying an L-shaped (two-level stepped) block. From above this block shows an extra dividing line where the two levels meet, so its plan is not a single plain inner square. This view does not match the given plan.
Answer: (4) the slab with the stepped block on top

- 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:
