The image shows the electric field lines around two charged particles.
at which position would the electric force be greatest?

a. 1

b. 2

c. 3

d. 4

D. 4

Explanation:

The electric force will be maximum at the position where the number of electric lines are maximum. As we can observe that the maximum number of lines are at position 4.

Thus, electric force is maximum at 4.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

the answer would be a
