<h2>
a)Acceleration due to gravity on the surface of the Sun is 274.21 m/s²</h2><h2>b)
Factor of increase in weight is 27.95</h2>
Explanation:
a) Acceleration due to gravity

Here we need to find acceleration due to gravity of Sun,
G = 6.67259 x 10⁻¹¹ N m²/kg²
Mass of sun, M = 1.989 × 10³⁰ kg
Radius of sun, r = 6.957 x 10⁸ m
Substituting,

Acceleration due to gravity on the surface of the Sun = 274.21 m/s²
b) Acceleration due to gravity in earth = 9.81 m/s²
Ratio of gravity = 274.21/9.81 = 27.95
Weight = mg
Factor of increase in weight = 27.95
Divide 56 by 60 then x the answer by 6 then you get 5.6km which is your answer.
A neutral atom is simply an atom that has no charge.
Answer:
Explanation:
<u>Given:</u>
Length of each side of the cube, 
The Elecric flux through one of the side of the cube is, 
The net flux through a closed surface is defined as the total charge that lie inside the closed surface divided by 
Since Flux is a scalar quantity. It can added to get total flux through the surface.

So the the charge at the centre is calculated.
