The equations are..For mass m is mgsina-T=m(2f) and for mass 2m is mg-2T=2m.f where a is angle of inclination and f is accelaration.From constraint it can be proved that booth will have same acc.

at mass 2M


let the angle of incline be @

therefore at mass M


adding 1 and 2



accleration of mass M and 2M will be samel ......

Is at the minimum deviation, angle of deviation is equal to angle of prism??
No that’s not always true. The minimum deviation is given when angle of incidence and angle of refraction would be equal. And that is given as: S = 2i – A hENCE not same with prism angle.
