Slope = △M/△X-¹ = M2 - M1 / X2-¹ -X1-¹

S = 120.0 - 40/80.0 - 27
= 80/53
S = 1.509 x 10³ = 1509

(1ax)
S = YMo
1509 = 30 Mo
Mo =1509/30
Mo =50.3

PRECAUTIONS
(i) I ensured that the metre rule balances horizontally before readings are taken in order to avoid experimental error.
(ii) I ensured that parallax error was avoided when taking the readings on the metre rule by viewing its calibrations vertically.

(1bi)
The moment of a force about a point is defined as the effect of force about that point.
Moment of a force = force × perpendicular distance of its line of action from the point.

Moment = F × h
The S.I unit is Newton-metre(Nm). It is a vector quantity

(1bii)
Draw the diagram

X = 50 - 25 = 25cm
y = 80 - 50 = 30cm
From the principle of moment :
Sum of clockwise moment = sum of anticlockwise moment
60x = M × y
60×25/30 = M×30/30
M = 60×25/30 = 6×25/3 = 2×25
M = 50g
