A turning effect depends on perpendicular distance - Paper 2

Read the information, then answer the questions. An adult may read the instructions aloud. Show your working where asked.

Read before answering

Ideal lever about a fixed pivot: a 20 N force produces a clockwise turn at perpendicular distance 0.15 m. A second force acts anticlockwise at perpendicular distance 0.3 m. Ignore the lever's weight. Moment = force x perpendicular distance; rotational balance requires equal opposite moments.
