1984 AP Physics B Free Response: Questions, Answers, and Analysis

The first question on the 1984 AP Physics B exam dealt with mechanics, specifically the motion of an object under the influence of a constant force. The problem stated: 1984 Ap Physics B Free Response Answers

F = (5.0 x 10^-9 C) x (1000 V/m) = 5.0 x 10^-6 N 1984 AP Physics B Free Response: Questions, Answers,

It’s a triangle in p-V? Actually, A→B is isobaric (horizontal), B→C is isochoric (vertical), C→A is isothermal (curved down). Net work = ( W_AB + W_BC + W_CA ). ( W_BC = 0 ). ( W_CA ) for isothermal: ( nRT_A \ln(V_A/V_C) ). But ( V_A=10 ), ( V_C=V_B=20 ). [ W_CA = (1)(0.0821)(244) \ln(10/20) = 20.03 \ln(0.5) = -13.88 , \textL·atm ] Net work = ( 20 + 0 + (-13.88) = 6.12 , \textL·atm \approx 620 , \textJ ). Answer: ( 620 , \textJ ) net work output per cycle. Net work = ( W_AB + W_BC + W_CA )

Using the Right-Hand Rule to determine the path of a positive charge.

This article provides a comprehensive breakdown of that exam’s free-response section. We will analyze each typical problem type from 1984, provide the correct answers, and explain the physics principles that generate those answers.
