Question

Calculate the acceleration due to gravity of sun. If Mass of sun = 2*10^30, radius of sun = 695000

Answer 1

Answer:

Acceleration due to gravity of Sun is 1.92 $\times 10^{11}$ $m/s^{2}$

Explanation:

Given that,

 Mass of Sun, M = $2 \times 10^{30}$ kg

Radius of Sun , R = 695000 km

Acceleration due to gravity , g = $\frac{GM}{R^{2} }$

                                                 $g=\frac{6\cdot 673\times 10^{-11}\times 2\times 10^{30}}{695000\times 10^3}$

                                                  g = 1.92 $\times 10^{11}$ $m/s^{2}$

Answer 2

GIVEN:

• Mass of the sun (M) = 2 × 10³⁰ kg

• Radius of sun (R) = 695000 km

TO FIND:

• Acceleration due to gravity (g) = ?

SOLUTION:

As we know that,

$\longrightarrow\sf{g = \frac{GM}{ {r}^{2} } } \\ \\ \longrightarrow\sf{g = \frac{6.673 \times {10}^{ - 11} \times 2 \times {10}^{30} }{695000 \times {10}^{3} } } \\ \\ \longrightarrow\sf{g = 1.92 \times {10}^{11} m {s}^{2} }$

• Hence, acceleration due to gravity on planet is 1.92 × 10¹¹ m/s².
