Question

if quantities A,Band C have non zero dimensions then which of the following euation is / are correct?a)

Answer 1

d)both 1 and 2 b'coz of homogenity

Answer 2

Hey.

Here is the answer.

(4) both 1 and 2

Explanation:

As two quantities with similar non-zero dimensions/ units can only be added or subtracted due to principle of homogeneity

so both 1 and 2 are correct

but if B and C will be multiplied then their dimensions will get squared as both has same dimension which will never be equal to the dimension of A .

Thanks .
