Two blocks are connected by a light inextensible string over a smooth frictionless pulley. Block \(A\) (mass \(m_{A}=4.0\ \text{kg}\)) hangs vertically, while block \(B\) (mass \(m_{B}=6.0\ \text{kg}\)) rests on a horizontal table. The coefficient of kinetic friction between block \(B\) and the table is \(\mu_{k}=0.20\). A horizontal force of magnitude \(10\ \text{N}\) is applied to block \(B\) to the right. Determine (a) the magnitude of the common acceleration of the system and (b) the tension in the string.

Answer Options

A. a = 2.1 m s⁻²; T = 18.5 N
B. a = 3.0 m s⁻²; T = 22.0 N
Correct Answer C. a = 3.74 m s⁻²; T = 24.2 N
D. a = 4.5 m s⁻²; T = 27.0 N
Correct Answer
C
Correct Option:
a = 3.74 m s⁻²; T = 24.2 N
