Two masses 2 kg and 4 kg are tied at the ends of a massless string and which is passing over a frictionless pulley. The tension in the string is

A

3.68 N

B

78.4N

C

26N

D

13.26 N

Text Solution

Verified by Experts

The correct Answer is:
C
Tension in the string `T = (2m_1 m_2)/((m_1 + m_2) ) g `
`T = (2 xx 2 xx 4)/(2 + 4) xx 9.8 = 16/6 xx 9.8 = 26.13 N`
