Question

A person has applied some mustard oil on his hands. Which of the following objects will become most difficult for him to hold in his hand?
A. Earthen cup (kulhar)
B. thermocol tumbler
C. glass tumbler
D. wooden cup

Answer 1

Answer:

glass tumbler

Explanation:

because glass tumbler is made up of glass so it is so slippery by applying oil we cant hold it

Answer 2

B. glass tumbler

Explanation:

Friction is a phenomenon which resists motion when an object is rubbed against another. So friction has instances where it is desired and instances where it is not desired. In this case, a person has applied oil on his hands which is a lubricant. So an object he handles will slide off his hand if it has a smooth surface. Wood, earthen cup and thermocol surfaces are slightly rougher than glass. Glass will slide off his hand and break.

Option C is the answer.
