a)
Yes. The magnitude of Torque is equal to the magnitude of the Force applied multiplied by the length of the lever arm.
So, when a small force is applied at a larger distance from the fulcrum, it may result in a greater torque than a larger force applied a nearer distance.
For example, a 20 Newton force applied to a 10 meter lever arm will have a larger torque than a 50 Newton force applied to a 2 meter lever arm.
