Question

an object of mass 10 kg is moving with a velocity of 10 m/s and another object of mass 20 kg is moving with a velocity of 5 m/s then the ratio of their momentum is a) 2:1 b) 1:1 c) 1:2 d) 3:2​

Answer 1

Answer:

B) 1:1

Answer 2

$\huge\mathfrak\red{ANSWER - }$

OPTION B

Explanation:

Momentum of a body is defined as the energy stored in it due to it's motion.

The momentum of a body is product of its mass and velocity. This is defined by the equation->

$p = m \times v$

Where (p) is momentum. (m) is mass and (v) is velocity.

Now, coming to question----->

Mass of first body = 10kg.

Velocity of first body = 10m/s

Therefore momentum of first body

$p = mv$

$p = 10 \times 10$

$p = 100kgm \div s$

Thus momentum of first body is 100kgm/s

Now for second body----->

Mass of second body = 20kg

Velocity of second body = 5m/s

Momentum of second body :

$p = mv$

$p = 20 \times 5$

$p = 100kgm \div s$

Thus momentum of second body = 100kgm/s.

Ratio of momentum of both bodies is = 100:100

RATIO = 1:1

Hence opt (b)
