Motion in Two Dimension — JEE physics STD 12 Science — Question

CBSE BoardEnglish MediumSTD 12 ScienceJEE physicsMotion in Two Dimension1 Mark
Question
Assertion : Two particles of different mass, projected with same velocity at same angles. The maximum height attained by both the particle will be same.
Reason : The maximum height of projectile is independent of particle mass.
✓

Answer

(a) $H=\frac{u^2 \sin ^2 \theta}{2 g}$ ie. it is independent of mass of projectile.
