1.	If momentum (P), area (A) and time (T) are assumed to be fundamental quantities, then energy has dimensional formula (A) [P1 A-1/2T-1] (B) [P1 A1/2T-1] (C) [P2 A-1 T-1] (D) [P1 A-1 T1]
Answer» Answer is (B) [P¹ A^1/2T^-1] [Energy] = [M¹ L² T^-2] = [M¹ L¹ T^-1] [L¹ ] [T^-1] = [P¹ A^1/2T^-1]

If momentum (P), area (A) and time (T) are assumed to be fundamental quantities, then energy has dimensional formula (A) [P1 A-1/2T-1] (B) [P1 A1/2T-1] (C) [P2 A-1 T-1] (D) [P1 A-1 T1]

Answer»

Answer is (B) [P¹ A^1/2T^-1]

[Energy] = [M¹ L² T^-2] = [M¹ L¹ T^-1] [L¹ ] [T^-1] = [P¹ A^1/2T^-1]
