Question

In the figure below, three 7.00 kg spheres are located at distances d1 = 0.100 m and d2 = 0.200 m. What are the magnitude and direction of the net gravitational force on sphere B due to spheres A and C?
magnitude N
direction degrees (counterclockwise from the +x-axis)

Answer 1

You need to do this in a couple steps.

First, find the force of gravity of A on B. This force will be in the vertical direction, pointing towards A.

Next, find the force of gravity of C on B. This force will be in the horizontal direction, pointing towards C.

Now you need to add those two forces by vector addition to get the magnitude and direction of the resultant vector, which will be the net gravitational force!

Answer 2

how do i find that? I havent been in class for 2 days and didn't learn how to do these

Answer 3

Does this equation look familiar:

\[F={Gm_1m_2 \over r^2}\]

Answer 4

yes bc of google haha

Answer 5

It's Newton's universal law of gravitation. F is the force of gravity between the two objects, G is the gravitational constant, the m's are the masses of the two objects, and r is the distance between the objects.

You can use this equation to find the forces I mentioned above!

Answer 6

Can u tell me the force on B due to object A

Answer 7

Let the force on object B due to the object A=F

Answer 8

Not F but it is F1

Answer 9

F1=G*m1*m2/d^2
F1=G*7*7/0.1^2

Answer 10

F1=?

Answer 11

Can u tell me the direction of F1

Answer 12

In the similar way u hv to find out the force between B and C

Answer 13

Response plz!!!!
