MAGNETIC EFFECT L-1

The dimension of magnetic field in M, L, T and C (Coulomb) is given as :

Consider atoms H, He^(+), Li^(++) in their ground states. If L_(1), L_(2) and L_(3) are magnitude of angular momentum of their electrons about the nucleus respectively then: A. L_(1)=L_(2)=L_(3) B. L_(1) gt L_(2) gt L_(3) C. L_(1) lt L_(2) lt L_(3) D. L_(1)=L_(2)=L_(3)

Arrange the following in the order as mentioned : -CN, -CI, -OH, -NO_2 groups in the order of decreasing -l-effect,

Consider the lines given by L_1: x+3y-5=0 L_2:3x-k y-1=0 L_3:5x+2y-12=0 Column I|Column II L_1,L_2,L_3 are concurrent if|p. k=-9 One of L_1,L_2,L_3 is parallel to at least one of the other two if|q. k=-6/5 L_1,L_2,L_3 form a triangle if|r. k=5/6 L_1,L_2,L_3 do not form a triangle if|s. k=5
