o toward the +6 HC charge 2. -1 points 16 18.3 P025. Point charges of 7. the positive charge. Include the sign of the value in your answers.) 00 C and-2.75 pC are placed 0.300 m apart. (Assume the negative charge is located to the right of (a) Where can a third charge be placed so that the net force on it is zero? m to the right of the -2.75 HC charge (b) What if both charges are positive? m to the right of the 2.75 uC charge My Notes Ask Your Teac os 016 18.3 WA.022. 3. 1.05/1 pointsI respectively. They then flew up Two birds walked across the carpet and became statically charged with a charge +q and -q ir square perch and landed on opposite corners. If a third bird with some net charge landed on the perch, would it tho nther hirds if it landed in the center of the perch or on one of the other corners?Explanation / Answer
(a)
let the third charge q is placed at x distance right to charge - 2.75 uC
so, F1 = F2
k*2.75*10-6 *q / x2 = k*q*7*10-6 / (0.3+x)2
2.75*(0.3+x)2 = 7x2
0.3+x / x = 1.59
x = 0.50 m to the right of charge 2.75
(b)
when both the charges are positive . let the third charge between the both charges .so
k*q*2.75*10-6 / x2 = k*q*7*10-6 / (0.3-x)2
2.75*(0.3-x2 ) = 7*x2
0.3 -x /x = 1.59
x = 0.11 m
