Nisolated, irregularly shaped piece of platinum carries −7.71×10−9 c of charge and is in electric equilibrium. the size of this body is about 4 mm. when the electric potential at some point on the metal's surface has the value , the potential at a different point on the surface may equal . always differs from . equals . when the electric field strength at some point on the body's surface has the value , the field strength at a different point on the surface equals 0. equals . may equal . always differs from . calculate the potential at a distance of 6.41 m from the center of the charged piece of platinum. potential:

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
