Question

Which one of the following pairs of physical quality have same dimension

Answer 1

Answer:

torque and energy

Explanation:

force = mass × acceleration 

energy = Workdone = force × displacement 

power = energy/time

torque = force × perpendicular distance between force and axis of rotation.

now, by these formula, find dimension of all terms.

e.g., dimension of force =[MLT⁻²] 

dimension of energy =[ML²T⁻²]

dimension of power =[ML²T⁻³]

dimension of torque =[ML²T⁻²]

dimension of energy and dimension of torque are equal.

Answer 2

Answer:

torque and energy

Explanation:

dimension of energy =[ML²T⁻²]

dimension of torque =[ML²T⁻²]
