Answer:
(a). The net gravitational force is 
(b). The position is at 0.232 m.
Explanation:
Given that,
Mass of one object M = 255 kg
Mass of another object M'= 555 kg
Separation = 0.390 m
(a). We need to calculate the net gravitational force
Using formula of force


Put the value into the formula


The net gravitational force is 
(b). We need to calculate the position
Force from 555 mass = Force from 255 mass




The position is at 0.232 m.
Hence, (a). The net gravitational force is 
(b). The position is at 0.232 m.
Answer:
magnitude=34.45 m
direction=
Explanation:
Assuming the initial point P1 of this vector is at the origin:
P1=(X1,Y1)=(0,0)
And knowing the other point is P2=(X2,Y2)=(19.5,28.4)
We can find the magnitude and direction of this vector, taking into account a vector has a initial and a final point, with an x-component and a y-component.
For the magnitude we will use the formula to calculate the distance
between two points:
(1)
(2)
(3)
(4) This is the magnitude of the vector
For the direction, which is the measure of the angle the vector makes with a horizontal line, we will use the following formula:
(5)
(6)
(7)
Finding
:
(8)
(9) This is the direction of the vector
