JEE Main 8 April 2026, Shift 2, Physics Q29

Question 29 of 75 in this shift, Physics question 4 of 25, Section A.

A gas balloon is going up with a constant velocity of 10 m/s. When this balloon reached a height of 75 m, a stone is dropped from it and balloon keeps moving up with the same velocity. The height of the balloon when the stone hits the ground is ________ m. (Take g=10g = 10 m/s2^2)
