Answer:
r =
Explanation:
Let's apply the universal gravitation law to the body (c), we use the indications 1 for the planet and 2 for the moon
∑ F = 0
-F_{1c} + F_{2c} = 0
F_{1c} = F_{2c}
let's write the force equations
where d is the distance between the planet and the moon.
(d-r)² =
d² - 2rd + r² = \frac{m}{M} \ \ r^2
d² - 2rd + r² (1 - ) = 0
(1 - ) r² - 2d r + d² = 0
we solve the second degree equation
r = [2d ± ] / 2 (1- )
r = [2d ± 2d ] / 2d (1- )
r =
there are two points for which the gravitational force is zero
I think it probably because the steel ship has more surface area then the the marble
hope i helped
Answer:
0.73m/s2
Explanation:
The speed at which the passengers move is the final speed of the plane
Hence acceleration = V-U/t; change in velocity and t is time taken. U is the initial velocity which is 0m/s
a = 73-0/100= 0.73m/s2
The relative magnitude of a vectorial field is proportional to the density of field lines. This is true also for the gravitational field: so, the spacing between the gravitational field lines indicates the intensity of the gravitational field. The smaller is the spacing between the lines, the stronger is the field's intensity, and viceversa.
