Find in degrees the angle through which a pendulum swings if its lengthis `50c m`and the tip describes an arc of length `10c m`. |
|
Answer» Here, length of arc, `l = 10cm` Length of pendulam, `r = 50cm` We know, `rtheta = l` `=>50theta = 10` `=>theta = 1/5 radian` `=>theta = 1/5(360/(2pi))^@ = (36/pi)^@` |
