2V, 1.0A
2V, 4.0A
6V, 0.3a
6V, 3.0a
Correct answer is A
cells in V = voltage of the cell
= 2V
I = \(\frac{v}{R} = \frac{2}{3}\)
= 1A

53.0N
21.0N
7.0N
5.0N
Correct answer is D
Vertical resultant = 10 - 6 = 4N
Horizontal resultant = 20 - 17 = 3N
R = \(\sqrt{3^2 + 4^2}\)
= 5N
2.4ms-2
5.6ms-2
8.0ms-2
2.4ms2
Correct answer is B
F + Ma = P
a = \(\frac{P - F}{m}\)
= \(\frac{40 - 12}{5} = 5.6ms^{-2}\)
