Particle a carrying a 3.0-μc charge is located at y = 3.0 m on the y axis of an xy coordinate system, and particle b carrying a 6.0-μc charge is located at the origin. a) what is the magnitude and direction of the electric force exerted on a?
express your answer with the appropriate units. enter positive value if the force is in +y direction and negative value if the force is in −y direction.

b) what is the magnitude and direction of the electric force exerted on b?
express your answer with the appropriate units. enter positive value if the force is in +y direction and negative value if the force is in −y direction.

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
