Explanation:
The calculated electric field is 3.0 N/C
<u>Explanation:</u>
The electric field is described only as the charge that it produces and is unique at every point in space. In particular, the electric field E is defined as the ratio of Coulomb forces to test charge. It can express as follows,
Where, F is the electrostatic (or Coulomb) force exerted on the positive test charge q. It is clear that E acts in the same direction of force. It is also assumed that q is so small and will not change the distribution of the charge generated by the electric field. It can express by a unit Newton per Coulomb (N / C).
Here, the given data, q = 2.0 C and F = 6.0 N. So, the electric field would be,
1) In any collision the momentum is conserved
(2*m)*(vo) + (m)*(-2*vo) = (2*m)(v1') + (m)(v2')
candel all the m factors (because they appear in all the terms on both sides of the equation)
2(vo) - 2(vo) = 2(v1') + (v2') => 2(v1') + v(2') = 0 => (v2') = - 2(v1')
2) Elastic collision => conservation of energy
=> [1/2] (2*m) (vo)^2 + [1/2](m)*(2*vo)^2 = [1/2](2*m)(v1')^2 + [1/2](m)(v2')^2
cancel all the 1/2 and m factors =>
2(vo)^2 + 4(vo)^2 = 2(v1')^2 + (v2')^2 =>
4(vo)^2 = 2(v1')^2 + (v2')^2
now replace (v2') = -2(v1')
=> 4(vo)^2 = 2(v1')^2 + [-2(v1')]^2 = 2(v1')^2 + 4(v1')^2 = 6(v1')^2 =>
(v1')^2 = [4/6] (vo)^2 =>
(v1')^2 = [2/3] (vo)^2 =>
(v1') = [√(2/3)]*(vo)
Answer: (v1') = [√(2/3)]*(vo)
