Question

how to solve questions like this? I'm getting stuck in every question of this type ☹️​

Answer 1

Take moments about O . you are confused in beggining only . practuce and practice and practice and once you will say the easiest questions ! - my experience (starting things always look difficult)

Answer 2

$\huge{\underline{\underline{\bold{\mathtt{\purple{✍A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍}}}}}}}}}}}}}}}}$$\huge{\rightarrow}$

Given that 40 gf is applied at a distance of 40 cm from point O. Hence moment of force is

40×40 = 1600gfcm

Hence this moment of force must be balanced by 80gf of force. After equating we get

1600gfcm = x×80gfcm

x = 1600/80cm

x = 20cm.

Hence 80 gf must be applied at a distance of 20 cm. This is all because of clockwise and anticlockwise moments are equal.

Dekho bss distance or force ko multiply krdo hrr sum me or jo bhi force de rkhi ho balance krne ke liye usko multiply by x krke equal me rkh do.. Bss answer aa jayega ..☺️

Or haa kisse dosti tut gyi tumhari ??
