Answer:
Explanation:
Torque created by force 3.34N
= 3.34 x 1.39 = 4.64 N.m
This torque is acting in clockwise direction .
Torque created by force 8.52 N
8.52 x .48
= 4.09 N.m
The force of 8.52 N is acting downward . It may turn the cylinder in clockwise or anticlockwise direction . So we shall consider both the possibilities.
If it rotates the cylinder in clockwise direction
Total torque = 4.64 + 4.09
= 8.73 Nm
If it rotates the cylinder in anticlockwise direction
Total torque = 4.64 - 4.09
= .55 Nm
Net torque will be in clockwise direction.
Answer:
Angle of refraction for red light is 
Angle of refraction for blue light is 
Explanation:
It is given refractive index for red light is 
Refractive index of blue light 
Angle of incidence 
According to law of refraction 
For red light 
Therefore angle of refraction for red light is
Similarly for blue light 
r =
Therefore angle of refraction for blue light is
