The diagram above illustrates a uniform metre rule which is balanced on a pivot by some masses. Calculate the value of M
A
500.0g
B
400.0g
C
44.4g
D
25.0g
correct option: d
clockwise moment = Anti-clock wise moment
= M x 40 = 100 x 10
M = \(\frac{1000}{40}\)
= 25g
= M x 40 = 100 x 10
M = \(\frac{1000}{40}\)
= 25g
