Question

Two objects A and B of masses 2 kilogram and 10 kilogram respectively are moving with same velocity. The ratio of their Momentum will be :​

Answer 1

Answer:

1:5

Explanation:

For object A,

m= 2kg

velocity = x (assume)

hence, momentum = p= mv = 2x

For object B,

m= 10kg

velocity = x (same as object A)

hence, momentum = p= mv = 10x

ratio of pA:pB

= 2x:10x

= 1:5

i hope this helps.

mark me as the brainliest.

Answer 2

Answer:

• The ratio of their Momentum will be 1 : 5.

Explanation:

Given that:

• Mass of object A = 2 kg
• Mass of object B = 10 kg
• Both the objects are moving with same velocity.

To Find:

• The ratio of their Momentum will be

Formula used:

• Momentum = Mass × Velocity

Let us assume:

• Both the objects are moving with velocity 'v'.

Finding the ratio of their Momentum:

= Momentum of A : Momentum of B

= (2 × v) : (10 × v)

Cancelling v.

= 2 : 10

= (2 × 1) : (2 × 5)

Cancelling 2.

= 1 : 5

∴ The ratio of their Momentum = 1 : 5
