I'm unsure of how to figure out the potential at the different corners because if the first distance is kq/1.5, why isnt the 2nd one kq/1.5? Im doing (9e9)(2.00e-6)/1.5=12000, which I dont know which number that is, or what to do with it further?

Two identical point charges are fixed to diagonally opposite corners of a square that is 1.5 m on a side. Each charge is +2.0 µC. How much work is done by the electric force as one of the charges moves to an empty corner? I have W(fe)= -EPE=-q[V(f)-V(i)]. I can't fig...

Megan factored the expression -12x^2 +52x-35as (-2x+5)(6x-7). But when Jacob applied the FOIL principle and multiplied out (-2x+5)(6x-7), he got -12x^2+44x-35; thus, Megan’s solution does not appear to check. Why is that? Please help Megan to understand this ...

Andrew factored the expression 20x^3-12x^2+8x as 4x (5x^2-12x^2+8x). But when Melissa applied the distributive law and multiplied out 4x (5x^2-12x^2+8x), she got 20x^3-48x^3+32x^2; thus, Andrew’s solution does not appear to check. Why is that? Please help Andrew to unders...

the planet Jupiter is more than 300 as massive as earth. But a body would scarecly weighs 3 times as much on the surface of Jupiteras it would on the surface of the earth. Can you think of an explanation for why this is so?
