An electrician has to repair an electric fault on a pole of height 4 m. He needs to reach a point 1.3 m below the top of the pole to un dertake the repair work the length of ladder that he should use, which when inclined at an angle of 60 to the horizontal would enable him to reach the required positions is :

$$ {9 sqrt{3} over 10}{ meter}$$

$$ {3 sqrt{3} over 10}{ meter}$$

$$ {3 sqrt{3} over 5}{ meter}$$

$$ {9 sqrt{3} over 5}{ meter}$$
