Answer to Problem 1MCQ

Option (c)

Explanation of Solution

Write the equation for a radian.

    θ=arc lengthradius        (I)

Therefore, the radian is a ratio of arc length to the radius.

Conclusion:

The ration of degree/time will have unit different from the unit of radian given using equation (I). Therefore, option (a) is incorrect.

Length has a different unit compared that of arc length given in equation (I). Hence, option (b) is incorrect.

The unit of length\length will be same as that of radian given using equation (I). Hence, option (c) is correct.

The length\time has a unit different from the unit of radian given using equation (I). Therefore, option (d) is incorrect.
