2.0N
3.0N
3.5N
7.0N
Correct answer is A
Upthrust = weight of liquid displaced
= mass of liquid displaced \(\times\) acceleration due to gravity
= \(\frac{200}{1000} \times 10\)
= 2N
4.0\(ms^{-2}\)
13.4\(ms^{-2}\)
16.0\(ms^{-2}\)
22.6\(ms^{-2}\)
Correct answer is B
Resolving 100N into horizontal and vertical
100 sin45 = 0.7071 * 100 = 70.71
100cos45 = 70.71
Vertical forces = 100 - 70.71 → 29.29
Horizontal force = 70.71 + 60 → 130.71
Resultant of vertical and horizontal forces using pythagoras thoerem
Resultant force (F) = m * a
a = F/m → 133.9/10
a = 13.4
