Box and use two decimal places for your final answers.

l. A square with a distance of 115 non on each side have point charges on each corner {except the lower left corner}. The position and the magnitude of the charges are as follows: +TD pC [upper right comer], 2 pC [upper left comer], and -3 pC ower right corner]. a. Calculate the potential difference at the lower left of the square in kilovolts. h. If a 5 pt? is at the lower left corner of the square, calculate the electric potential as we move it to the center in DJ or nanojoules. 2. Four point charges are placed on a cattesian coordinate plane. The position and the magnitude of the charges are as follows: +10 pf; at [1]}, 2L'! all at {LT}, 3{} at? at [523] and +4 oil at [2,T]. The scale of coordinates is lunit:1em. a. Calculate the potential difference at point A [22] and point B [4,3} in ICU. b. If a It] all: charge is place on point A, how many joules are needed to move it from point B
