Most Important Selected Qs for JEE AdvancedPhysicsWork, Power and Energy
A hollow tube containing a ball is kept on smooth horizontal surface. Now, tube is accelerated horizontally and ball is slightly displaced from point 'A'. Let N₁ and N₂ be the magnitude of normal force applied by inner and outer surface respectively. Then, which of the following is/are correctly represent approximate nature of N₁ and N₂ Vs (0 )
Correct answer
3
Step-by-step solution
From Work energy theorem array ll m a₀ R(1- )= 1 2 m v^2 v^2=2 a₀ R(1- ) & ---(1) m a₀ -N₁= m v^2 R & ---(2) N₁=(3 -2) m a₀ & when = 2 3 & N₁=0 for ⁻¹ ( 2 3 ) & N₁=0 N₂=m a₀(2-3 ) & array
