Escape velocity from the earth surface is ______?

زمین کی سطح سے فرار کی رفتار ______ ہے؟

9.1 km/sec

11.2 km/sec

1.7 km/sec

None of these

Escape velocity is the minimum speed required for an object to escape Earth's gravitational field without further propulsion.

On Earth, this velocity is 11.2 km/s.

It calculated using the formula vₑ = √(2GM/R), where G is the gravitational constant, M is Earth's mass, and R is its radius.
