Three point charges have equal magnitudes, two being positive and one negative. these charges are fixed to the corners of an equilateral triangle, as the drawing shows. the magnitude of each of the charges is 3.0 μc, and the lengths of the sides of the triangle are 1.0 cm. calculate the magnitude of the net force that each charge experiences.

answer would be d.) i hope this

explanation:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

statement #3 on andre"s list is false.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
