Any physics student knows that light travels in a straight line. But now researchers have shown that light can also travel in a curve, without any external influence. The effect is actually an optical illusion, although the researchers say it could have practical uses such as moving objects with light from afar.
Answers & Comments
Radius = 6 cm.
Chord = 8 cm.
Perpendicular distance =?
We know that, the perpendicular bisects the chord,
So, In ∆ABC = BC = 8/2
BC =4 cm.
AC = ?
Using PGT
AB^2 =AC^2 +BC^2
6^2 = AC^2 + 4^2
36=AC^2 +16
36-16= AC^2
20=AC^2
√20=AC
2√5 = AC
So, perpendicular= 2√5 cm.
