Question

Question:

What is the strength of the electric field at the position indicated by the dot in Figure 1?

Express your answer using two significant figures.

E = _____ N/C

Part B) What is the direction of the electric field at the position indicated by the dot in the figure? Specify the direction as an angle above the horizontal line.

Express your answer using two significant figures.

θ = _____ 

Answer and Explanation:

The separation of position (shown by the spot) from the two point charges is same: r=5√2 cm.
Likewise, the charges of two-point charges is same: q=+1.0 Nc.
In this way, the quality of electric field of the two point charges is additionally same at the position demonstrated by speck:
E=kq/r2
=9×109×1.0×10−9/(5(√2) ×10−2)2
=1.80×103N/C
By evenness the electric fields by two point charges makes an edge of 45∘ with flat, one in upward heading and the other descending way.
In this way, their vertical part will offset and flat segment will include.
Section A) Thus the quality of the electric field at the position shown by the spot in Figure is:
Enet=2Ecos45∘
=2× (1.80×103) × (1/√2)
=2.55 × 103N/C
Part B) The heading of the electric field at the position demonstrated by the speck in the figure is along the level line as vertical segments of the electric field offset one another.
Along these lines, θ=0.00∘
