Why do electric field lines cannot cross?

They cannot cross because they have different values. Each line has its own value and if they could cross, that would mean that we can have 2 different values at the same point (and it cannot be true).

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2

Ithink it’s b hope it
