Two blocks, one with a mass of 6 kg and one with a mass of 9 kg, are connected by a rope and are sitting on a frictionless surface. you attach a second rope to the 6 kg block and start pulling with a force of 30 n. what is the tension in the rope between the blocks? ?

Explanation:

Net tension force applied on 6 kg block is given as

here we will have

now we will have

Now the tension between two blocks will pull the other end mass i.e. 9 kg

so we will have

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
