Question

(iii) Considering first correlation, complete the second :
Acceleration due to gravity : m/s :: Gravitational constant​

Answer 1

Unit of gravitational constant=m³/kg·s².

Answer 2

Answer:

Acceleration due to gravity  = m/sec²  , Gravitational constant = Nm²/kg²

Explanation:

Acceleration due to gravity

• It is defined as acceleration produced in freely falling bodies .
• It is denoted by "g" and its unit is m/sec².
• Acceleration due to gravity is different at different places .like on earth it is 9.8m/sec².
• Its values is maximum at poles that is 9.8 meter  per second squares and minimum at equator that is 9.7 meter per second square and in centre of earth it is zero .

Gravitational constant

• It  is numerically equal to force of attraction between two bodies of masses 1 Kg separated by distance 1m.
• It is denoted by G and its units are newton meter square per kilogram square .
• It is same at all places .Its value is 6.67 x 10⁻¹¹.
