Hello,
I would like to ask anyone that could help me with my Physics II HW. I am really struggling to understand it and I would need help with my grades. Thanks. If you could put advice/books/ videos etc to help me understand it, that would be great.

When submitng an answer like 3540000000 , you can Type iT in as is or using scien±fc noTa±on like 3.54e9 . IF your answer is 0.00000542 , you can also Type iT in like 5.42e-6 . Numerical answers musT be Typed To The mosT accuraTe value. Numerical answers wiThin 3% oF The acTual answer are counTed as correcT. ²o avoid rounding errors in calcula±ons, use aT leasT three (3) signifcanT fgures For numerical answers. Each answer in this assignment is worth a maximum of one point. 1 . Three vectors →A , →B , and →C have the following x and y components: x - component y - component A -5 9 B 2 -5 C 4 1 What is the magnitude of →R = →A - →B + →C ? 2 . A vector →A has a magnitude of 49.0 m and points in a direction 20.0° below the positive x axis. A second vector, →B , has a magnitude of 70.0 m and points in a direction 46.0° above the positive x axis. Find the magnitude of the vector →D = →A - →B . m 3 . The electrostatic force between two charges located 4.0 meters apart is 0.16 N. What will the force be between these charges when they are located 1.2 meter apart? Newtons
4 . Three point-like charges are placed at the corners of a square, 32.0 cm on each side. Find the magnitude of the net electrostatic force exerted on the point charge q 3 . Let q 1 = 31.0 µC, q 2 = 38.0 µC, q 3 = 45.0 µC. N 5 . Two charged objects attract each other with a force F. What happens to the force between them if one charge is doubled, the other charge is tripled, and the separation distance between their centers is reduced to one-fourth its original value? The force is now equal to 24 F 6/16 F 96F 16 F
