in the reference frame of the sphere, there are two forces: g(downward gravity) and horizontal inertial force a,

let the particle slide an angle theta, Work done by the two forces=mRasinθ +mRg(1-cosθ)=mv2/2,

v2=2R(asin(theta)+g(1-cos(theta)), v=√(2R(asinθ+g(1-cosθ)))

 

in the end put a = g as given in the question
