JEE Main 2021 — Laws Of Motion Question with Solution
From: JEE Main 2021 (Online) 24th February Morning Shift
Question
An inclined plane is bent in such a way that the vertical cross-section is given by where y is in vertical and x in horizontal direction. If the upper surface of this curved plane is rough with coefficient of friction = 0.5, the maximum height in cm at which a stationary block will not slip downward is _________ cm.

Correct answer
25
Step-by-step explanation
The graph for given equation is shown below
At maximum height, the slope of tangent drawn,
[ ]
( = tan)
x = 1 m
= 0.25 m = 25 cm
At maximum height, the slope of tangent drawn,
[ ]
( = tan)
x = 1 m
= 0.25 m = 25 cm
