Can electric field lines ever cross? Why or why not

Whether the electric field lines will cross each other and describe the reason.
Answer to Problem 1FTD
Field lines never cross each other.
Explanation of Solution
Field lines never cross each other. If they cross each other, at that particular point the field lines have more than one direction. According to the properties of field lines, field lines should have only one direction.
Direction of the field lines from the positive charge to the negative charge. Therefore, electric field lines ever cross each other.
Conclusion:
Therefore, electric field lines never cross each other.

- Required information Two speakers vibrate in phase with each other at 523 Hz. At certain points in the room, the sound waves from the two speakers interfere destructively. One such point is 1.45 m from speaker #1 and is between 2.00 m and 4.00 m from speaker #2. The speed of sound in air is 343 m/s. How far is this point from speaker #2? marrow_forwarda) Consider the following function, where A is a constant. y(x,t) = A(x — vt). Can this represent a wave that travels along?
