If the units of force, energy and velocity are 20N, 200J and 5ms^(-1) , find the unit of length, mass time.

If the unit of force energy and velocity are 20 N, 200J and 5m//s, find the units of mass, length and time.

If the units of force, energy and velocity are 10 N, 100 J and "5 ms"^(-1) respectively. Then obtain the units of length, mass and time.

If the units of force, energy and time are 20N, 100 J and 10s, find the units of mass and length.

If the unit of force is 2N, that of length is 4m and that of velocity is 6ms^(-1) , the unit of mass is

If the unit of force is 2N, that of length is 4m and that of velocity is 6ms^(-1) , the unit of mass is
