25. Suppose two students are trying to make a new measurement
system so that they can use it like a code measurement
system and others do not understand it. Instead of taking
1 kg, 1 m and 1 sec as basic units they took unit of mass
as a kg, the unit of length as B m and unit of time as y
second. They called power in new system as ACME.

Given: Instead of taking  1 kg, 1 m and 1 sec as basic units they took unit of mass  as a kg, the unit of length as b m and unit of time as y  second.

To find: 1 N in new system and 1 J in new system.

Solution:

  • Now we have given that instead of taking  1 kg, 1 m and 1 sec as basic units they took unit of mass  as a kg, the unit of length as b m and unit of time as y  second.
  • Consider 1 N, we write it as:

                   1 N = mass x acceleration

                   1 N = kg x m/s^2

  • Now according to new system, we have:

                   1 N = (kg'/a x m'/b ) / (s')^2/r^2

                   1 N = ( a^-1 x b^-1 x r^2 ) x kg'm'/(s')^2

  • New system will be: a^-1 x b^-1 x r^2
  • Consider 1 J, we write it as:

                   1 J = kg x m^2/s^2

  • Now according to new system, we have:

                   1 N = (kg'/a x (m')^2/b^2 ) / (s')^2/r^2

                   1 N = ( a^-1 x b^-2 x r^2 ) x kg'(m')^2/(s')^2

  • New system will be:  a^-1 x b^-2 x r^2

Answer:

             So 1 N in new system will be a^-1 x b^-1 x r^2 and 1 J in new system will be a^-1 x b^-2 x r^2 .

Answer:

below:

Explanation:

I am also a student i am not sure about my answer but i will try the 2023 jee   batch, 1KG=alpha

then 1=alpha/kg

or 1=kg/alpha (means either you write q/p or p/q both are same if the result is one)

now why i reversed it obviously to make it more like a newton

same again 1M=bita

then 1=bita/metre

or 1=metre/beta explained earlier

again this time we want time as a denominator so we won't change

1 sec=Gamma

1=Gamma/sec

force=[M1L1T-2]

=kg/alpha*metre/bita*(gamma/second)^2

=(kg*metre*gamma^2) /(alpha *bita*second^2)

=kg m/sec^-2  *gamma^2 alpha^-1 bita ^-1

=newton gamma^2 alpha ^-1 bita ^-1 :    kg m/sec^-2==newton

=so for 1 newton  alpha is -1 bita is -1 gamma is 2
