find μ 4 Years, 8 Months ago

 
A non conducting ring(mass m,radious r,having charge Q) is placed on a rough horizontal surface(in a cylindrical region with tranverse magnetic field ).The field is increasing with time at the rate R and the coefficient of friction b/w the surface and the ring is μ.For ring to remain in equilibrium μ should be greater than (1)Qr2R2/2mg (2)QrR/2mg (3)Qr2R/2mg (4)QrR2/2mg guys..Pls tell me the steps also?
