NCERT · Class 11 · Physics · Motion in a Straight LineA body is dropped from a height h. The time taken by the body to reach the ground is proportional to:
Step-by-Step Solution
Using equation of motion h = 1/2 g t^2, we get t = sqrt(2h/g). Thus, t is proportional to sqrt(h). Therefore, the correct option is sqrt(h).
