For the arrangement shown in the Fig. the tension in the string is- [Given: tan –1 (0.8) = 39 0 ]
Text Solution
Verified by ExpertsThe correct answer is:
D
If alpha represent angle of repose, then, 
The given angle of inclination is less is less than the angle of repose. So, the 1 kg block has no tendency to move. [note that 
is exactly balanced by the force of friction. So, 
.]
