Question

Coulomb constant is 8.98755 X 10⁹ Nm² / C² .
The 1.94 μC charge is at the origin and a -5.76 μC charge is 10 cm to the right, as shown in the figure.


A. Identify the direction of in the region II (0<x< 10cm, along the x-axis)
choices are: All possibilities, none of these, up, down, left, right


B. Identify the direction of in region III(x>10, along the x-axis)
Same choices

C. Locate the x coordinate such that = 0.
Note: q₁ is at the origin O. Answer in units of cm

Answer 1

@ Ans: Right WAL ® Ans: left © Here, 9,= 1.94 MC and P = -5.76 MC KX-216 toon OS ret, electric field is zero at a point exed to the left of 96. then; : *9= $92 (2+10)2 .. (1.94) = 5.76 32 (x+10)? .: (1.94) (x2 +20x+100) = 5.7622 ::1.94x2 + 38.8%+ 194 = 5.76x? .: 3.8272 – 38.8% -194=0 .; X = 13.839 cm therefore, the x-coordinate will be: /* = -13.829 cm Ans.
