For the body to just topple or translate, the force equations are same. The force equation for just toppling or just translation is
F - f = 0
=> F = f ....(1)
N - mg = 0
⇒ N = mg; f ≤ µmg
If µ =0.2, Maximum frictional force = 0.2 mg
Therefore using equation (1) the force required to move the body by translation is F = 0.2 mg.
The Force required to topple the body is F = 0.5 mg.
Therefore transalation happens first. The body will translate and not topple.
