Question

Q1: Using the known values of the mass of the earth and the radius of the earth, calculate the

value of g.

The radius of the Earth is 6.37 × 106 m

The mass of the Earth is 5.96 × 1024 kg

G = 6.67259 x 10-11 N m2

/kg2

the universal gravitation constant
.

Q2: What is the change in g if the measuring apparatus is raised in height by 1 meter?​

Answer 1

Answer:

m g = G * m * M / R^2      force of attraction

g = G * M / R^2

g = 6.67E-11 * 5.96E24 / (6.37E6)^2

g = 6.67 * 5.96 / 6.37^2 * 10^1

g = .98 * 10 = 9.8 m/s^2

Q2.

d g = G M * (-2 R^-3 dR ) = -2 G M / R^3       (very small where dR = 1)
