Force of gravity would be = > mgsin30 => 50/2 = 25 N.
Work Done by the force of gravity would be
=> F * 10 => 25 * 10 => 250 joule

Dear Student,
Work,W=force×distance
Force, F=weight of the block
F=5×9.8
F=49 N
Since, weight acts in a vertical direction, we need to know the distance travelled vertically.
distance, d=10 sin30°
d=10×0.5=5 m
W=49×5=245 J
