Question

Force Fis given in terms of time t and 2 points distance x by F= A sin Ct + B cos Dt Then the dimensions of A/B and C/D are
1)MLT-2 &. MLT-1
2)MºL°T° and MºLT-1
3)MLT-2 & LT
4)Dimensional less​

Answer 1

Explanation:

dimensions of [A] = [B] = [F]

dimensions of [C] = [D] = [T⁻¹]

because of same units

∴ [A] /[B] = dimensional less

[C] / [D] = dimensional less
