3 charges, 1.0 µC each, are located on three vertices A, B, C of an equilateral triangle with sides 2 cm each. Another charge q is located at the mid point of the side BC. Calculate q so that net force on the charge at A due to the charges at B, C and D is zero

Use the ratio form of kepler’s third law, = , and the data provided to determine the time it takes mars to orbit the sun. round your answer to the nearest tenth. earth’s orbital period = 1.0 earth year earth’s distance from the sun = 1.0 au mars’s distance from the sun = 1.5 au it takes mars about ⇒ 1.8 earth years to orbit the sun.
