In a nuclear fusion reactor,the Lawson criterion prescribes the necessary conditions,as related to density and confinement time of the plasma fuel,in order that the process produces a net power output.If the fuel density were doubled,by what factor would the required confinement time change?
A)0.25
B)0.50
C)1.4
D)2.0

The Lawson criterion suggests that the product of the plasma fuel density (n) and the confinement time (τ) must exceed a certain value for net power output. If the fuel density is doubled, the required confinement time is halved to maintain the same product nτ, hence the factor is 0.50.
