G varies directly as the square of j and inversely as m. If g=0.05 when j = 0.4 and m=1.6, what is g when j =6 and m=4

The value of G = 4.5

Step-by-step explanation:

As per given,

When we replace proportional sign with an equal to sign, we get

, where k = constant

If G=0.05 when j = 0.4 and m=1.6, then

Now,

hence, when j =6 and m=4, the value of G = 4.5
