medium Difficulty
Verified Correct Answer: Option D
Physical Principles & Numerical Solution
To keep the block of mass m in equilibrium against a vertical wall using a horizontal force F:
The normal reaction N = F
The frictional force f must balance the weight: f = mg
Maximum friction available: f = \muN = \muF
For the minimum horizontal force:
\muF = mg
F = mg / \mu

medium Difficulty
Verified Correct Answer: Option C
Physical Principles & Numerical Solution
From the diagram given in the question
Change in length = (6.5 - 5.0) x 10\(^{-2}\)m
Change in force(wg) = (420 - 200) x 10 x 10\(^{-3}\) = 2.5N ( g changed to kg)
extension per unit x = \(\frac{\Delta l}{\Delta F}\) = \(\frac{1.5 \times 10^{-2}}{2.5}\) = 6.0 x 10\(^{-3}\)

medium Difficulty
Verified Correct Answer: Option B
Physical Principles & Numerical Solution
In solids, sound can exist as either a longitudinal or a transverse wave. But in mediums which are fluid (e.g., gases and liquids), sound waves can only be longitudinal. For Longitudinal Waves, the displacement of the medium is parallel to the direction of propagation of the wave.
