The dimension of the quantity `vecExxvecB`, where `vecE` represents the electric field and `vecB` the magnetic field is

Options

A. `[MT^(-3)]`
B. `[M^(2)LT^(-5)A^(-2)]`
C. `[M^(2)LT^(-3)A^(-1)]`
D. `[MLT^(-2)A^(-2)]`

Answer

B

Explanation

` 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)`
