Answer:
Option B,D
Explanation:
[n]=[L−3];[q]=[AT]
[ϵ]=[M−1L−3A2T4]
[T]=[L]
[l]=[L]
[kB]=[M1L2T−2K−1]
(a) RHS
√[L−3A2T2][M−1L−3T4A2][M1L2T−2K−1][K]
√[L−3A2T2][L−1A2T2]
√[L−2]=[L−1] Wrong
(b) RHS
√[M−1L−3T4A2][M1L2T−2K−1][K][L−3A2T2]
√[L−1A2T2][L−3A2T2]=[L] Correct
(c) RHS
√[A2T2][M−1L−3T4A2][L−2][M1L2T−2K−1][K]
√[L3] Wrong
(d) RHS
√[A2T2][M−1L−3T4A2][L−1][M1L2T−2K−1]
√[A2T2][L−2A2T2]= [L] Correct
