A constant force of magnitude

20\,\text{N}

makes an angle of

30^{\circ}

with the horizontal and produces a horizontal displacement of

5\,\text{m}

in a block. The work done by the force on the block is closest to (a)

1.0\times10^{2}\,\text{J}

(b)

5.0\times10^{1}\,\text{J}

(c)

8.7\times10^{1}\,\text{J}

(d)

1.2\times10^{2}\,\text{J}
