Question

find the answer test plssssss​

Answer 1

given➡

as rod is in equilibrium mean there is no weight acting of mass M. since mark is at 60 cm from origin and mass is at 90cm

explanation➡

let mass of rod is M',

since mass of rod across mark is m

.....(toward right)

mass remaining M'-m

......(toward left)

rod rain in equilibrium when

M'-m=M

.......(here M is mass at 90cm from origin)

since in 100cm rod only 60%of length has mass equal to other mass M.

THEN MASS OF ROD IS MORE THAN MASS AT MARK M
