Take a block of ice and place it on a smooth surface, push the block with some net force. Now increase the net force and push it again.

(D) Scripting, (E) Programming

Correct Answer - अयूब ने ज्यादा दूरी तय की। यह दूरी 0.9 km या 900 m ज्यादा थी।

Given: m = 20 kg, FL = 100 N, μk = 0.4 To find: i. Coefficient of static friction (μS) ii. Minimum force required (Fk) Formulae: i. μs = \(\frac{F_L}{N}=\frac{F_L}{mg}\) ii. μS = \(\frac{F_K}{N}\) Calculation: From formula (i), μs = \(\frac{100}{20\times9.8}\) = 0.5102 From formula (ii), Fk = μkN...

Correct option is: (A) 0.6

Correct option is A) 500 NS

A) A and R are true, R supports A

A) force increases, friction increases

D) Both Assertion and Reasons are correct and “R” is correct explanation for Assertion.

D) Increases then remains constant

Correct Answer - Delegation.
