Question

Two bodies of masses 4 kg and 6 kg are attached to the ends of a string passing over a pulley. The 4 kg mass is attached to the table top by another string. The tension in this string T, is equal to (Take g = 10 ms?) т 4Kg. 6Kg A) 20N T B) 251 10 CD 10N​

Bbb

Answer 1

Answer:

EXPLANATION.

=> Two bodies of masses 4kg and 6kg are

attached to the ends of a string passing

over a pulley.

=> The 4 kg mass is attached to the table Top

by another string.

To find the tension in the string.

=> For a 6 kg of block

=> T = 6g

=> T = 60 N ........(1)

=> For a 4 kg of block

=> T - T¹ - 4g = 0

=> T = T¹ + 4g

=> 60 = T¹ + 40

=> T¹ = 60 - 40

=> T¹ = 20N

Therefore,

option [ A ] is correct answer.

Answer 2

Answer:

Option A ) 20N is the correct answer

for a 6kg of block

T=6g. T=60N.........1

for a 4kg of block

T- T1- 4g =0

T=T1 +4g

60=T1 +40

T1 =60-40

T1= 20 N
