In a new system of units, unit of mass is taken as
100 kg, unit of length is taken as 50 m and unit of
time is 10 seconds. What will be the weight (in new
system of unit) of a body in this system, if in Si
system, weight is 800 N?
Answer:
Answers
weight (in new system of unit) of a body in this system is 16 N
Explanation:
800N = 800 kg m /s²
Let say in SI unit Mass , Length & Time are M . L & T
M L / T² = 800
Now a new system of units, unit of mass is taken as 100 kg,
So new Mass would be M /100
unit of length is taken as 50 m
=> New Length = L/50
unit of time is 10 seconds.
=> New Time = T/10
weight (in new system of unit) = (M/100) ( L/50) / ( T/10)²
= (ML/T²) /50
= 800/50
= 16
weight (in new system of unit) of a body in this system = 16
