Question

please give answer this question​

Answer 1

y= a sin( At- Bx + C)

As sin( At- Bx+ C) is dimensionless

and At- Bx+ C is angle So dimensionless

So here each term would be dimensionless

At ,t dimension is T

So A. would be T^-1 to make it dimensionless

Bx , x dimension L

So B dimension is L^-1

And C is dimensionless So M^0 L^0 T^0

So its B)

Answer 2

answer is option B

the term (At-Bx+C) must be dimensionless so each term is dimensionless

so At is dimensinoless so dimensions of A=[ T-1]

and similarly Bx is dimensionless and dimensions of B=[L-1]

and also C is dimensionless
