दो विद्यार्थी एक जैसे बक्सों को 10 m की दूरी तक ले जाते हैं। विद्यार्थी A, 50 N का बल अनुप्रयुक्त करता है, जबकि विद्यार्थी B, 100 N का बल अनुप्रयुक्त करता है। दोनों विद्यार्थियों द्वारा किए गए कार्य में कितना अंतर है?
Two students carry identical boxes over a distance of 10 m. Student A applies a force of 50 N, while student B applies a force of 100 N. What is the difference in the work done by the two students?
- (A)1000 J
- (B)50 J
- (C)0 J
- (D)500 J
Show answer and explanation
Answer: (D)
500 J
W = F × s। छात्र A: 50 × 10 = 500 J; छात्र B: 100 × 10 = 1000 J। अंतर = 1000 − 500 = 500 J।
W = F × s. Student A: 50 × 10 = 500 J; student B: 100 × 10 = 1000 J. Difference = 1000 − 500 = 500 J.
