Answer:
Explanation:
Given:
- mass of nerf projectile,
- velocity of nerf projectile,
- mass of the gun,
Now in this case the collision can be assumed to be perfectly elastic.
<u>For an elastic collision:</u>
where:
recoil velocity of the gun

Answer:
Explanation:
q₁ = 8 x 10⁻⁶ C , q₂ = 3.5 x 10⁻⁶ C , q₃ = -2.5 x 10⁻⁶ C
Force between charge = 9 x 10⁹ x q₁ q₂ / d²
Force on q₁ due to q₂
= 9 x 10⁹ x 8 x 10⁻⁶ x 3.5 x 10⁻⁶ /( .10 )²
= 25.2 N . This force will be negative as it will point towards left ( q₂ will repel q₁ )
Force on q₁ due to q₃
= 9 x 10⁹ x 8 x 10⁻⁶ x 2.5 x 10⁻⁶ /( .15 )²
= 8 N . This force will be negative as it will point towards left ( q₃ will attract q₁ )
Net force = 25.2 N - 8 N
= 17.2 N .
