Find the gravitational field strength due to the sun at the surface of the earth. Given mass of the sun is 2 x 10³⁰kg.

Solution

Here,
Mass of the sun, $straight M equals 2 cross times 10 to the power of 30 kg$
The distance of the earth from the sun is, $straight R equals 1.5 cross times 10 to the power of 11 straight m$

Therefore, gravitational field strength due to the sun is,
$straight E equals GM over straight R squared equals fraction numerator 6.67 cross times 10 to the power of negative 11 end exponent cross times 2 cross times 10 to the power of 30 over denominator left parenthesis 1.5 cross times 10 to the power of 11 right parenthesis squared end fraction$
$equals 5.93 cross times 10 to the power of negative 3 end exponent straight N divided by kg$
