4mm
3mm
2mm
1mm
Correct answer is B
\(I_2 - I_1 = I_1, \theta\alpha - 1 \times 100 \times 3 \times 10^{-5}\)
= 3 x 10-3m
= 3mm
14.0\(\Omega\)
6.7\(\Omega\)
3.2\(\Omega\)
2.7\(\Omega\)
Correct answer is B
\(\frac{R - 4}{10 - 4} = \frac{45 - 0}{100 - 0}\)
R = \(\frac{670}{100} = 6.7\Omega\)

2.0kgms-1
10.0kgms-1
5.0kgms-1
2.5kgms-1
Correct answer is B
I = Ft = m(v - u) = 5 x 2
= 10kgms-1
