Question

7) Draw an arrow to show the gravity field gi due to mass mi, at point 3, (Should the arrow be longer or shorter than what you did in 5a?) 8) Find the total vector expression of the gravity field vector due to mass m, at point 3. 913 Please draw two arrows to show its x and y components respectively j (N/kg) 913 = 9) Around mi (the dot on the left) using many arrows to show the direction and strength of the gravity field created by mi. 10) Please use words to DISCRIBE the gravity field created by mi. The point mass m creates gravity field along the direction the gravity field strength will be The closer to m, the th of the gravity field due to mi will

Explanation / Answer

7 )

the gravitation fields g1 is due to the mass m1 at point 3 directs towards origin

8 )

total vector expression at point 3 is by mass m1 is

F = GM m r^ / r2

we have

F = M g

g = F / M

g13 = G m1 m3 r^ / m3 r2

g13 = G m1 r^ / r2 N/kg
