Question 4 WAEC_MODEL_QUESTIONS_VOL1 • 2024 • PHYSICS • practical

A spring balance is used to determine the spring constant of a helical spring. Masses are hung from the spring and the corresponding extensions are recorded as follows: | Mass (kg) | Extension (cm) | |-----------|----------------| | 0.10 | 2.0 | | 0.20 | 4.1 | | 0.30 | 6.0 | | 0.40 | 8.2 | | 0.50 | 10.1 | Take g = 9.8 m s⁻². Assume the spring obeys Hooke’s law (F = kx).

Question Parts

( a )

Using the data above, determine the spring constant k (in N m⁻¹). Show the method you use.

( b )

Calculate the mass that would stretch the spring by exactly 5.0 cm.

( c )

State two precautions that should be observed when using a spring balance for such measurements.

( d )

Explain why a graph of extension (x) against load (F) is expected to be a straight line.
