three charged particles lie on the same straight line. their charges are equal:
qa=qb=qc=0.5 microcoulombs
charged particle b is in between particles a and c, in the middle. what is the intensity of the electrostatic force acting on particle a? the distance between a and c is 20 meters. particles b and c are fixed in place.
formula for the electrostatic force:
the answer is 28 micronewtons, but i don't understand how they got that solution?

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
