Answer:
27 . 10^-7 or 27/1000
Explanation:
We use the Coulomb Law
k = Coloumb Constant
q1 and q2 are the charges
d is the distance between the spheres
Answer:
C. The initial momentum should be equal to the final momentum due to the conservation of momentum.
Since m/(M+m) < 1, v_1 > v_0.
Explanation:
Wrong -> A. Since the smaller particle still moves after the collision, it has a kinetic energy.
Wrong -> B. The total initial momentum is equal to the momentum of the smaller particle. Therefore, the momentum of the objects that stuck together is equal to that of the smaller object.
Wrong -> D. Since the bigger object is initially at rest and the surface is frictionless, the direction of motion will be the same as the direction of the smaller particle.
