Can you explain why option C is wrong in today's DPS Q7? The one about electric field lines.
Great question! Option C says "Electric field lines can intersect each other." This is incorrect because:
• Electric field lines never intersect — at the point of intersection, there would be two different directions of the electric field, which is impossible.
• I see you've made a similar mistake in Electrostatic Potential (Day 3) — want me to pull up that question for revision?
Yes please! And give me a similar practice question.
Here's your previous mistake from Electrostatic Potential (attempted 19 Jul):
"Two point charges +4μC and -2μC are placed 10cm apart. Where is the electric field zero?"
🔄 Similar question: Three charges +2q, -q, and +3q are placed at vertices of an equilateral triangle. Find the point where net electric field is zero.
Want me to walk through the solution step by step? 🤔
