The dimensions of the quantity `vecE xx vecB`, where `vecE` 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)LT^(-3)A^(-1)]`

D

`[MLT^(-2)A^(-2)]`

Text Solution

Verified by Experts

The correct Answer is:
B

` vecE xx vecB = EB sin theta `
`rArr [vecE xx vecB] = [E] [B] = MLT^(-3)A^(-1)xx MA^(-1)T^(-2)`
` " " = M^(2)LT^(-5)A^(-2)`
