- INSTRUCTIONS: Show your complete solution to each problem on a short bond paper. Answers must be expressed in engineering notation (when the exponent of the base 10 multiplier is not a multiple of 3, press ENG or SHIFT+ENG, whichever the case.) Example: 0.06N or 6.0x10-2 N must be expressed to 60x10-3 N or 60mN 5. At a corner of a 30 mm x 40 mm rectangle is placed a charge of -40µC and at the two adjacent corners are charges of +20µC, as shown in the figure. Determine: a. The potential at the 4h corner P. b. The potential at the center of the rectangle. c. The work that must be done by an external force to bring a charge q1 = +5µC from the center of the rectangle to the 4h corner P. 91 = +20 µC 92 = -40 µC в 30 mm P 40 mm 93 = +20 µCarrow_forwardDetermine the order of magnitude of the following small number by entering the appropriate exponent n below: 6,370km≈10nkm 6,370km≈10nkm .arrow_forwardAnswers must be expressed in engineering notation (when the exponent of the base10 multiplier is not amultiple of 3, press ENG or SHIFT+ENG, whichever the case.)Example: 0.06N or 6.0x10-2 N must be expressed to 60x10-3 N or 60mNDecimal places = 2 to 5arrow_forward
