Answer:
Torque has the dimension of force times distance, symbolically L2MT−2. Official SI literature suggests using the unit newton metre (N⋅m), or, joule per radian (J/rad). The unit newton metre is properly denoted N⋅m rather than m.
Mass m is in kg and acceleration a is in metre /second^2, therefore the dimensional formula of force is MLT^-2 hope this helps you!
