Three blocks A, B and C are pulled on a horizontal smooth surface by a force of 80 N as shown in figure Image The tensions T₁ and T₂ in the string are respectively:

Question

G1 Physics · Accepted Answer

Image Total mass: M = 5 + 3 + 2 = 10 kg Acceleration: a = F/M = 80/10 = 8 m/s² For block A: T₁ = 5 × 8 = 40 N For block B: T₂ - T₁ = 3 × 8 T₂ = 24 + 40 = 64 N Therefore, T₁ = 40 N, T₂ = 64 N
