3. A simply supported beam is five meters in length. It carries a uniformly distributed load including its own weight of $300 \mathrm{~N} / \mathrm{m}$ and a concentrated load of 100 N, 2 meters from the left end. Find the reactions if reaction $A$ at the left end and reaction $B$ at the right end. $R A=810 \mathrm{~N}, \mathrm{RB}=790 \mathrm{~N}$ $\mathrm{RA}=820 \mathrm{~N}, \mathrm{RB}=690 \mathrm{~N}$ $R A=830 N, R B=680 N$ $R A=840 \mathrm{~N}, R B=670 \mathrm{~N}$
