Question

The dimensions of the quantity vec E × vec B where vec E represents the electric field and vecB the magnetic field may be given as: (A) [ MT 3] (B) [ M 2 LT -5 A -2] (C) [ M 2 L -3 T 2 A -1] (D) [ MLT -2 A -2]

Tardigrade Admin · Accepted Answer

Correct answer is (b) [ M 2 LT -5 A -2]

Q. The dimensions of the quantity $E \times B$ where $E$ represents the electric field and $B$ the magnetic field may be given as:

$[M T^{3}]$

$[M^{2} L T^{- 5} A^{- 2}]$

$[M^{2} L^{- 3} T^{2} A^{- 1}]$

$[M L T^{- 2} A^{- 2}]$

Correct answer is (b) $[M^{2} L T^{- 5} A^{- 2}]$

Q. The dimensions of the quantity E×B where E represents the electric field and B the magnetic field may be given as:
