Assertion: Pressure is scalar. Reason: Pressure acts equally in all directions at a point.
A. A true, R false
B. Both true, R doesn't explain A
C. Both true, R explains A
D. A false, R true
Answer: Option C
Solution (By JKSSB Mock Tests)
Pressure is scalar (no direction), though force is vector. Reason: Pascal's law - fluid pressure transmits equally in all directions, confirming scalar nature. Memory aid: 'Pressure = force/area (scalar division); isotropic in fluids'. Assertion-reason testing fluid mechanics fundamentals, common in competitive exams.
