Question

State whether the following statement is true or false. The escape velocity of a body from the earth surface,v EAS=2√Gm/R

Answer 1

Dear Student,

◆ Answer -

Given statement is FALSE.

● Explanation -

Escape velocity of the body is -

ve = √(2GM/R)

ve = √(2gR)

Escape velocity of a satellite from earth's surface is calculated by-

ve = √(2gR)

ve = √(2×9.8×6.4×10^6)

ve = √125.44 × 10^3

ve = 11.2 × 10^3 m/s

ve = 11.2 km/s

Escape velocity of satellite from earth's surface is 11.2 km/s.

Hope that is useful...
