An object is projected such that it has to attain maximum range. Another body is projected to reach maximum height. If both the objects reached the same maximum height, then the ratio initial velocities

A \(2: 1\)
B \(\sqrt{2}: 1\)
C \(1: \sqrt{2}\)
D \(1: 2\)

Verified Solution

Answer & Solution

Correct Answer

(B) \(\sqrt{2}: 1\)

Step-by-step Solution

Detailed explanation

For first object, if range is maximum, then \(\theta=45^{\circ}\) \(\therefore \mathrm{H}_1=\frac{\mathrm{u}_1^2 \sin ^2 \theta}{2 \mathrm{~g}}=\frac{\mathrm{u}_1^2 \sin ^2 45^{\circ}}{2 \mathrm{~g}}=\frac{\mathrm{u}_1^2}{4 \mathrm{~g}}\) For second object,…

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
