A)It will increase as the slope angle is lessened.
B)It will decrease as the slope angle is lessened.
C)It is not affected by the slope angle.
D)It will possibly increase or decrease as slope angle is lessened,depending upon other factors.

The gravitational force pulling the particle downward along the land surface will decrease as the slope angle is lessened because the component of the force acting parallel to the slope reduces with a decrease in the inclination of the slope. However, the perpendicular component of the force acting normal to the slope remains the same regardless of the slope angle.
