State the meaning of electrostatic potential at a point.
Answer
Electrostatic potential at a point is the work done in bringing a unit positive charge from infinity to that point without acceleration. Formula: V = work done per unit charge Unit: volt (V) = J C^-1…
किसी बिंदु पर स्थैतिक विद्युत विभव का अर्थ बताइए।
Answer
किसी बिंदु पर स्थैतिक विद्युत विभव वह कार्य है जो अनंत से उस बिंदु तक एक इकाई धन आवेश को बिना त्वरण के लाने में किया जाता है. सूत्र: V = प्रति इकाई आवेश किया गया कार्य इकाई: volt (V) = J C^-1…
एक बिंदु आवेश Q = 4 × 10^-7 C किसी बिंदु से 9 cm दूर रखा गया है। उस बिंदु पर विभव ज्ञात कीजिए।
Answer
दिया है: Q = 4 × 10^-7 C, r = 9 cm = 0.09 m सूत्र: V = Q / (4π ε0 r) चरण 1: V = (9 × 10^9 N m^2 C^-2) × (4 × 10^-7 C / 0.09 m) चरण 2: V = 4 × 10^4 V उत्तर: 4 × 10^4 V…
A point charge Q = 4 × 10^-7 C is placed 9 cm from a point. Find the potential at the point.
Answer
Given: Q = 4 × 10^-7 C, r = 9 cm = 0.09 m Formula: V = Q / (4π ε0 r) Step 1: V = (9 × 10^9 N m^2 C^-2) × (4 × 10^-7 C / 0.09 m) Step 2: V = 4 × 10^4 V Answer: 4 × 10^4 V…
Why is electrostatic work path independent?
Answer
Work done by an electrostatic field depends only on the initial and final points, not on the path. Reason: electrostatic force is conservative. Meaning: the same potential difference is obtained for a…
स्थैतिक विद्युत कार्य पथ-स्वतंत्र क्यों होता है?
Answer
स्थैतिक विद्युत क्षेत्र द्वारा किया गया कार्य केवल प्रारंभिक और अंतिम बिंदुओं पर निर्भर करता है, पथ पर नहीं. कारण: स्थैतिक विद्युत बल संरक्षणशील होता है. अर्थ: समान दो बिंदुओं के बीच किसी भी पथ के लिए…
एक आवेश 2 × 10^-9 C को अनंत से उस बिंदु पर लाया जाता है जहाँ V = 4 × 10^4 V है। किया गया कार्य ज्ञात कीजिए।
Answer
दिया है: q = 2 × 10^-9 C, V = 4 × 10^4 V सूत्र: W = qV चरण 1: W = (2 × 10^-9 C)(4 × 10^4 V) चरण 2: W = 8 × 10^-5 J उत्तर: 8 × 10^-5 J…
A charge 2 × 10^-9 C is brought from infinity to a point where V = 4 × 10^4 V. Find the work done.
Answer
Given: q = 2 × 10^-9 C, V = 4 × 10^4 V Formula: W = qV Step 1: W = (2 × 10^-9 C)(4 × 10^4 V) Step 2: W = 8 × 10^-5 J Answer: 8 × 10^-5 J…
