These are problems concerning calculation of torque. You can find first the component of force that is perpendicular to the R. Then multiply that force component with R to get torque ||\tau=F_\perp R||.

Once have torque, you can use ||\tau_{net}=I\alpha|| to get the angular acceleration.

Here, the moment of inertia of the wheels will be approximated with a ring -- ||I=mR^2||.
