Question

What will be happen to limiting friction if :
(a) - Area of contact is doubled
(b) - Weight of the body is doubled​

Answer 1

$\huge\star{\red{\underline{\mathfrak{Answer}}}}$

What will be happen to limiting friction if :

(a) - Area of contact is doubled

➡If the area of contact is double the limiting friction also gets doubled .

(b) - Weight of the body is doubled

➡The friction remains unchanged if weight of the body is doubled .

Answer 2

$\huge\underline\mathfrak\green{Solution}$

•If the area of contact is doubled, then the limiting friction also gets doubled.

->Because they are directly proportional to each other

•The limiting friction does not depend upon the weight of the body

-> So if the weight of the body is doubled then also the limiting friction remains unchanged
