$(a)$ स्थिरवैध्यूत क्षेत्र रेखा एक संतत वक्र होती है अर्थात कोई क्षेत्र रेखा एकाएक नह्है टूट सकती। क्यों?

$(b)$ स्पष्ट कीजिए कि दो क्षेत्र रेखाएँ कभी भी एक-दूसरे का प्रतिच्छेदन क्यों नहीं करती?

Option A
Option B
Option C
Option D

Solution

$(a)$ An electrostatic field line is a continuous curve because a charge experiences a continuous force when traced in an electrostatic field. The field line cannot have sudden breaks because the charge moves continuously and does not jump from one point to the other.

$(b)$ If two field lines cross each other at a point, then electric field intensity will show two directions at that point. This is not possible. Hence, two field lines never cross each other.
