Question 2 NECO • 2021 • PHYSICS • practical

In a force table experiment, two forces are applied as follows: - Force \(F_{1}\) = 5.0 N acting due east. - Force \(F_{2}\) = 3.0 N acting at 45° north of east. The resultant force is measured with a spring scale and recorded as 7.6 N. The student must:

( a )

Resolve \(F_{2}\) into its eastward and northward components.

( b )

Determine the theoretical magnitude of the resultant of \(F_{1}\) and \(F_{2}\).

( c )

Calculate the percentage difference between the measured resultant (7.6 N) and the theoretical resultant.

( d )

State two possible reasons for the discrepancy between the measured and theoretical resultant.
