Question

5) The gravitational force between two objects that

are 2.1x10 m apart is 3.2x10N. If the mass of one
object is 55 kg what is the mass of the other object?

Answer 1

F=G
`(M1XM2)/(R^(2) )`

Step-by-step explanation:

F=F=G
`(M1XM2)/(R^(2) )`

Newton law define gravity as the product of two mass and the mean squired distance between the two bodies.

Where F is the gravitational pull and G is the gravitational constant and M1 and M2 are masses of two bodies while R is their mean distance

Replacing the value in the equation it becomes:

3.2x10N=G
`(M1X55)/(2.1X10^(2) )` Where G is the gravitation constant,
`6.67x10^(-11)`

M1=
`(3.2X10X(2.1X10)^(2) )/(55)`

M1=
`3.8468x10^(-11)`Kg
