Answer 1

Answer:

Explanation:

Here, the ruler is pivoted at its midpoint and a 50 gf and is suspended at one end.

in order to keep the ruler horizontal, the net moment at the mid point should be zero.

let "x" be some length from the suspended point

50gf × (L/2) = 100gf × a

a = L/4

since the length of the ruler is 1 metre. so, a = 0.25m = 0.25 x 100= 25 cm
