Question

a mass of planet if 6×10²⁴ kg and its diameter is 12.8×10³ km...calculate the value of accelaeation due to gravity on the surface of this planet​

Answer 1

Answer:

Ok

Explanation:

Acceleration due to gravity,

g=G×

R

2

M

Mass, M=6×10

24

kg

Diameter = 12.8×10

3

km = 12.8×10

6

m

Radius, R=(12.8×10

6

)/2=6.4×10

6

m

Gravitational constant, G=6.7×10−11Nm

2

/kg

2

g=6.7×10

−11

×

(6.4×10

)

2

6×10

24

g=

6.4×6.4

6.7×60

g=9.8m/s

2

As the value of g=9.8m/s

2

, the planet could be Earth.
