If earth stops rotating, the apparent value of g will increase. Because of earth's rotation, there is a centrifugal force acting on us which tries to throws us outward(against gravity). If earth stops, there will no force centrifugal force acting and the apparent value of g will increase.

g = G Me/Re²
Me = mass of Earth, R = radius of Earth
G = universal Gravitation constant
Some part of the weight a person or object on Earth is consumed in providing the centripetal force towards center of Earth, for each of us is moving in a circle of radius R, where 0 <= R<= Re . Value of R depends on latitude.
Effective value g' = g - R ω² , where ω = 2π/86400 rad/sec
The force we exert on the surface of Earth will be m g' = this is our weight.
If Earth stops rotating, then g' = g and so it increases.
