IB Physics HL D 1 12 Hl Equipotentials and Field Lines Questions

Practise IB Physics HL D.1.12 by interpreting equipotential diagrams, field-line direction, potential differences and work.

Exam points

Explain why a gravitational field line is perpendicular to an equipotential surface.
Read potential differences from equipotential diagrams and relate them to field direction.
Use field-line/equipotential geometry to determine force direction and work along a path.

[Maximum number: 1]

The diagram shows 5 gravitational equipotential lines. The gravitational potential on each line is indicated. A point mass m is placed on the middle line and is then released. Values given in $\mathrm{MJ} \mathrm{kg}^{-1}$ .
