Mychool oo,,,,,the options are not correct,,,,,,the right ansa is 2.5N
applying the principle of moments and taking moment about the pivot
sum of clokwise mment=sum anticlkwse mment
sotherfore,(25x1)+(Wx2)=(20x1)
25+2W=20
2W=20-25
2W/2=-5/2
sotherfore W=-2.5N downward OR 2.5N upward

Clockwise moments= Anticlockwise moments
W×2= 20 × 1
Cross multiply
W=20÷2
=10N

this is actually what is in the past questions though
clockwise moments=anticlockwise moments
(w*2) = (20*1)
w=20/2
=10N

(25×2) + w = 20 × 2
~ be aware of the distance away from gravity G
50 + w = 40
w = 10N
