GRE GR 1777, Problem 001 Solution

Physics GRE GR 1777

  1. Classical Mechanics (Force)

Solution) The force F_{A} is

F_{A} = m_{A} \cdot a_{A}

Since m_{B} = 2 m_{A} and a_{B} = 2 a_{A},

F_{B} = m_{B} \cdot a_{B} = (2 m_{A}) \cdot (2 a_{A}) = 4 m_{A} \cdot a_{A} = 4 F_{A}.

Therefore, the answer is (E).
