Three blocks are pushed with a force \(\mathrm{F}\) across a frictionless table as shown in figure. Let \(\mathrm{N}_{1}\) be the contact force between the left two blocks and \(\mathrm{N}_{2}\) be the contact force between the right two blocks. Then

  1. A \(F>N_{1}>N_{2}\)
  2. B \(F>N_{2}>N_{1}\)
  3. C \(\quad F>N_{1}=N_{2}\)
  4. D \(F=N_{1}=N_{2}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(F>N_{1}>N_{2}\)

Step-by-step Solution

Detailed explanation

\(\mathrm{F}=6 \mathrm{a}, \mathrm{N}_{1}=5 \mathrm{a}, \mathrm{N}_{2}=3 \mathrm{a}\) \(\mathrm{F}>\mathrm{N}_{1}>\mathrm{N}_{2}\)
