GATE 2026 Biomedical Engineering (BM) Question Paper with Solution PDF

The GATE 2026 Biomedical Engineering (BM) Question Paper with Solution PDF is available here following the conclusion of the exam. The GATE BM paper was scheduled for February 14, 2026, in the Afternoon Session (AN) from 2:30 PM to 5:30 PM.

Based on previous years' analysis, the BM paper is typically expected to be of moderate difficulty. Candidates aiming for admissions to top-tier IITs or recruitment by relevant PSUs should target a score between 55–65+ marks. Attempting 50–60 questions with an accuracy of 85–90% is generally considered a safe and competitive range.

2.
Two cars, P and Q, start from a point X in India at 10 AM. Car P travels North with a speed of 25 km/h and car Q travels East with a speed of 30 km/h. Car P travels continuously but car Q stops for some time after traveling for one hour. If both cars are at the same distance from X at 11:30 AM, for how long (in minutes) did car Q stop?

Consider two infinitely long fins made of the same material and exposed to the same convective environment. One fin has a square cross-section of side \(a\), and the other has a circular cross-section of diameter \(d\). Assume \(a = d\). The ratio of the steady-state heat transfer rate from the square fin to that from the circular fin, \(\frac{\dot{Q}_{\text{square}}}{\dot{Q}_{\text{circular}}}\), is:

\(\frac{\pi}{4}\)
\(\frac{4}{\pi}\)
\(\frac{2}{\sqrt{\pi}}\)
\(\frac{\sqrt{\pi}}{2}\)

6.
During a welding operation, thermal power of 2500 W is incident normally on a metallic surface. As shown in the figure below (figure is NOT to scale), the heated area is circular. Out of the incident power, 85% of the power is absorbed within a circle of radius 5 mm while 65% is absorbed within an inner concentric circle of radius 3 mm. The power density in the shaded area is _________ W mm^-2 (rounded off to 2 decimal places).
