A 2-kg mass and a 4-kg mass on a horizontal frictionless surface are
connected by string A having negligible mass. The 2-kg mass is on the right,
and is pulled horizontally to the right by a second string B (also having
negligible mass), resulting in a constant acceleration of 12 m/s².


What is the magnitude of the tension in string B on the 2-kg mass?
a. 72 N
b. 48 N
c. 24 N
d. 6 N
e. 3 N - correct answer ✔A
