Question

3. Calculate the value of g on the surface of an imaginary planet of mass 1 x 1024 kg and radius 2 x 10 m. Take
G = 6.7 x 10-11 N m² kg-?
4. A stone is gently dropped from a height of 80 m. tf its velocity increases uniformly at the rate of 10 m s?, with
what velocity will it strike the ground?​

Answer 1

Answer:

g = 6.7 × 256 × 10^-13

Step-by-step explanation:

• we know that g=G . M/ r^2. therefore, g on planet = G . M / r ^2. g=6.7 × 10 ^-11 × 1024 / 2× 10 × 2×10. g = 6.7×256 ×10^-13.
