A charge of -3.50 nC is placed at the origin of an xy-coordinate system, and a charge of 1.95 nC is placed on the y axis at y = 3.55 cm. Part A
If a third charge, of 5.00 nC, is now placed at the point x = 2.85 cm , y = 3.55 cm find the x and y
components of the total force exerted on this charge by the other two charges.
Part B
Find the magnitude of this force.
Part C
Find the direction of this force.

cant without the picture! ?

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
