Question 3/50 Expert Physics Chapter1: Electric Charges and Fields Gauss's Law and its Applications Class 12 Level 24

खुली सतह पर गाउस नियम को बंद आवेश वाले रूप में सीधे क्यों नहीं लगाया जाता?

Why is Gauss's law in enclosed-charge form not applied directly to an open surface?

Explanation opens after your attempt

Correct Answer

A. क्योंकि बंद आवेश स्पष्ट करने के लिए पृष्ठ का बंद होना जरूरी हैBecause the surface must be closed to define enclosed charge clearly

Step 1

Concept

गाउस नियम कुल अभिवाह को बंद पृष्ठ से जोड़ता है। / Gauss's law connects total flux with a closed surface.

Step 2

Why this answer is correct

बंद पृष्ठ ही किसी आयतन को पूरी तरह घेरता है। / Only a closed surface completely encloses a volume.

Step 3

Exam Tip

इसलिए खुली सतह पर बंद आवेश वाला रूप सीधे लागू नहीं किया जाता। / Hence the enclosed-charge form is not directly used for an open surface.

Open Question Page

Step 3

Exam Tip

दूरी दोगुनी होने पर क्षेत्र एक चौथाई रह जाएगा। / Doubling distance makes field one-fourth.

Open Question Page

Question 7/50 Expert Physics Chapter1: Electric Charges and Fields Gauss's Law and its Applications Class 12 Level 24

चालक के अंदर विद्युत क्षेत्र शून्य है। क्या यह जरूरी है कि चालक पर कुल आवेश भी शून्य हो?

Electric field inside a conductor is zero. Is it necessary that total charge on the conductor is also zero?

Explanation opens after your attempt

A. नहीं, अतिरिक्त आवेश सतह पर रह सकता हैNo, excess charge can stay on the surface

Step 1

Concept

स्थिर अवस्था में चालक के भीतर क्षेत्र शून्य होता है। / In electrostatic equilibrium, field inside a conductor is zero.

Step 2

Why this answer is correct

यह बात केवल अंदर के क्षेत्र के बारे में है। / This statement concerns the internal field.

Question 9/50 Expert Physics Chapter1: Electric Charges and Fields Gauss's Law and its Applications Class 12 Level 24

बंद पृष्ठ का क्षेत्रफल दोगुना कर दिया गया पर अंदर का शुद्ध आवेश वही है। कुल अभिवाह क्यों नहीं बदलता?

A closed surface area is doubled but the net charge inside remains the same. Why does total flux not change?

Explanation opens after your attempt

Correct Answer

A. क्योंकि कुल अभिवाह बंद आवेश से तय होता है, क्षेत्रफल से नहींBecause total flux is determined by enclosed charge, not area

Step 1

Concept

गाउस नियम कुल अभिवाह को बंद आवेश से जोड़ता है। / Gauss's law connects total flux with enclosed charge.

Step 2

Why this answer is correct

क्षेत्रफल बदलने से स्थानीय क्षेत्र या वितरण बदल सकता है। / Area change may alter local field or distribution.
