Correct answer: a

Surface tension = force/length = [MLT⁻²]/[L] = [MT⁻²]।

Correct answer: a

Viscous force = η A(dv/dx) থেকে η-এর dimension [ML⁻¹T⁻¹]।

Correct answer: b

Kinematic viscosity = dynamic viscosity/density = [ML⁻¹T⁻¹]/[ML⁻³] = [L²T⁻¹]।

Correct answer: c

Volume হলো তিনটি length-এর গুণফল, তাই [L³]।

Correct answer: b

Area = length × length, তাই [L²]।

Correct answer: c

Radian = arc/radius; দুই length-এর ratio হওয়ায় angle dimensionless।

Correct answer: c

Solid angle = area/radius², তাই dimension [1]।

Correct answer: a

Charge = current × time, তাই dimension [AT]।

Correct answer: a

Volt = work/charge = [ML²T⁻²]/[AT] = [ML²T⁻³A⁻¹]।

Correct answer: a

Resistance = volt/current = [ML²T⁻³A⁻¹]/[A] = [ML²T⁻³A⁻²]।
