From: JEE Main 2021 (Online) 16th March Morning Shift
Question
A block of 200 g mass moves with a uniform speed in a horizontal circular groove, with vertical side walls of radius 20 cm. If the block takes 40 s to complete one round, the normal force by the side walls of the groove is :

Show full solutionCorrect option: C
Correct answer
C9.859 104 N
Step-by-step explanation
Normal force will provide the necessary centripetal force.
N = m2R
Also, =
N = (0.2)(0.2)
N = 0.2 0.2
N = 9.859 104 N
N = m2R
Also, =
N = (0.2)(0.2)
N = 0.2 0.2
N = 9.859 104 N
