QUESTION STATEMENT:द्विभाषी / Bilingual
पदार्थ के संवेग (Momentum) और वेग के अनुपात में कौन-सी भौतिक राशि प्राप्त की जाती है?
Which physical quantity is obtained from the ratio of momentum and velocity of a body?
SELECT CORRECT OPTION:
A
वेग
Velocity
B
त्वरण
Acceleration
C
द्रव्यमान
Mass
Correct
D
बल
Force
Official Solution & Explanation:
Correct Answer: Option C(द्रव्यमान)
किसी वस्तु के द्रव्यमान ($m$) तथा वेग ($v$) के गुणनफल को संवेग ($p$) कहते हैं ($p = m \times v$)। अतः $\frac{\text{संवेग}}{\text{वेग}} = \frac{m \times v}{v} = m$ (द्रव्यमान)।
Since momentum is the product of mass and velocity ($p = m \cdot v$), the ratio of momentum to velocity yields mass ($\frac{p}{v} = m$).
