Here ,
as the charges are oposite sign ,
the electric field will be zero on one side of the charges
As the charge 5 uC is smaller , the electric field will be zero somewhere left of 5 uC
hence , point lies as a dot in the image
Ignore red X Click on the area where the electric field is zero. Careful, you have...
5 4. In a certain place the surface area is not zero, the electric field is not zero, and the electric flux is zen What can you say about the orientation of the electric field with respect to the surface? 5. Three equal charges are placed at the corners of a triangle that has each side 1.2 m long. Calculate the value of the electric potential on the x-axis, half-way between the charges Q1 and Q2 況3 2
1) Discuss the following: Is it possible to have zero electric field at a point where the potential does not equal zero? Discuss. Is it possible to have zero potential at a point where the E-field is not zero? Discuss. Provide examples if possible. Include in your discussion an analysis of the equivalent questions for "topo" maps. [l.e. what would be "zero potential", "zero field", etc.]
Where is the electric field zero?
If a rectangular area is rotated in a uniform electric field from the position where the maximum electric flux goes through it to an orientation where only half the flux goes through it, what has been the angle of rotation?
7. Find the point on the x axis where the electric field is zero. The point lies between 91 and q2. 91 = +8 nC P2 P1 x, m 3 4 5 6 7 8 N 92 = +12 nc
Calculate the electric potential at the points where the electric field is zero. q1 and q2 are located on the x-axis at (-1,0,0) and (1,0,0) respectively. (a) q1-q2-1 nC (b) q1 = 1 nC, q2 =-1 nC (c) -10nc, 92 -1nc (d) 10nC, 21nC (e) 1nC, 92-10 nc (f) 110 nC, q2 1 nc
3.4 The electric field in a region of space is zero for x < 0 and x 〉 9 m, and is Ezー-80 V/m for 0 〈 x 〈 3.0 m and is Ez +40 V/m for 3.0 〈 x 〈 9.0 m. (a) If the potential at zero for x 0 make a quantitative sketch of the electric potential for-1.0 〈 x 〈 10 m. (b) What distribution of charges produces the electric field? Hints: What type of charge...
For a and b below, roughly where is the electric field zero? Mark with an E. Roughly where is the potential zero? Mark with a V. (If is nowhere near the charges, indicate this.) (Be sure to be clear if it's just one point, or something else.) Then sketch the electric field lines (solid) and equipotential lines (dotted) around the two point charges. а. ь.
What is the direction of the electric field at the position of the red X? -Q tQ
You measure only in x-direction and find that the electric field is given as Ae-jßz where A, B are positive constants. What kind of wave is it? TM none of the above TEM TE
