Question

If bullet of mass 'm₁' is fired from a gun of mass 'm₂' with a speed of 'V₁', then the recoil velocity of gun is ______.

विकल्प

• -`("m"_1"V"_1)/"m"_2`

• -`("m"_2)/("m"_1"V"_1)`

• -`("m"_1)/("m"_2"V"_1)`

• -`("m"_2"V"_1)/"m"_1`

Answer 1

If bullet of mass 'm₁' is fired from a gun of mass 'm₂' with a speed of 'V₁', then the recoil velocity of gun is `underline(-("m"_1"V"_1)/"m"_2)`.

Explanation:

m₁V₁ - m₂V₂ = 0

`therefore "V"_2 = (- "m"_1"V"_1)/"m"_2`
