a block A kept on inclined surface begins to slide if inclination is 30 degrees.block A is replaced by another block B.and it is found that it just begins to slide if inclination is 40 deg. then----a)mass of A>mass of B b)mass of A
Dear tushar
Equation of motion for Block A is when it just atart sliding
mag sin30 -μamagcos30=0
sin30 -μacos30=0............1
Equation of motion for Block B is when it just atart sliding
mbg sin40 -μbmbgcos40=0
sin40 -μbcos40=0............2
clearly these equation does not depends upon mass of block so all three condition can be possibel
