PLEASE HELP ASAP 4. Which statement best describes elastic and inelastic collisions most accurately? a. Momentum is not conserved in both elastic and inelastic collisions
b. Momentum is only sometimes conserved in both types of collisions, because sometimes
an object slows down after a collision, which means the object lost momentum.
Momentum is always conserved in elastic collisions, but only sometimes conserved in
inelastic collisions because momentum is lost when the objects stick together.
d. Elastic collisions have objects that bounce apart after the collision, while in inelastic
collisions the objects stick together. Momentum is conserved in both types of collision.
C.

The correct answer should be b let me know if i’m wrong

Answer: a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same sign as the  -4.0  µc charge.======electricstatic force between two point charges  is given by    where k is coulomb's constant,  8.99×10⁹  n·m²/c², q₁ and q₂ are the point charges, and r is the distance between the two point charges.assign positive to q₁let q₁ =  6.0 µc, q₂ = -4.0  µc, q₀ represent the charge at the origin, and q₃ represent this new charge to place.the charge at the origin q₀ would experience the following force f₀₁ from q₁, with r = 6.0 m (note that 1  µc = 10⁻⁶ c)    the force from q₂    the force from q₃    the net force on the origin charge, q₀, has to be zero for no electrostatic forcehaving an equation where k and q₀ can be divided out of the equation will allow us to solve for q₃    isolating:     a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same as the  -4.0  µc charge
