If the unit of mass is doubled and the units of length an time are halved,how much is 20 N of force in new units? `(1" N= 1kg" m s^(-2))`

If the unit of length is doubled and that of mass and time is halved, the unit of energy will be

If the fundamental units of length, mass and time are doubled, the unit of force will

The value of force in a certain system of measurement is 200 units. If unit of mass is doubled the unit of length is trebled, the unit of time is halved then the value of force in new system of units is x^(1//3) , then the value of x is

A force of 40N acts on a body. If the units of mass and length are doubled and the unit of time is tripled, then the force in the new system becomes

A force of 40N acts on a body. If the units of mass and length are doubled and the unit of time is tripled, then the force in the new system becomes

If the units of length, mass and time are doubled, then the new unit of work expressed in terms of L, M and T
