Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.what do u mean seems wrong ðŸ˜
they have just written an equation where the minimum force required to lift the block up and solved it
also the monkey moving up with a particular acceleration is the same as a man pulling the rope with the same acceleration, u can think of it that way (if that was ur doubt)
@Gaurav what do u think is wrong ?
like doing a pull up
not necessarily
i dont think i got ur pull up reference lmao
1) the weight of the monkey is 50N then how is tension 100N
2)the monkey is moving upward means he is pulling the rope downwards? @g-sus ?
i mean like roughly the monkey is climbing with more and more power(acc) upwards?
tension is 100N cus monkey is also moving up with 10ms^-2 ( which is what lets it lift the block)
10ms^-2 is the minimum acceleration needed to start lifting the block and that will remain constant, it doesnt need increasing power....
the 2nd statement stated here is the perfect explanation honestly
shouldnt it be in equilibrium if a is 10?
bro just roughly i am talking not the work/timewala power
its a fine line yk, similar to friction where on reaching limiting friction the body can either remain at rest or move with an infinetismally small acceleration
like monkey should have a little more very very littl emore acc?
yep
again they ahve asked minimum acceleration hence u state 10 as ans
i dont thinnk that right still lol
I think more accurate would be >10
like i said at that point the block can either stay at rest or move with negligible acceleration and thats what is considered
oohhh
for the block to actually move >10 is appropriate
and if the monkey was just hanging then the tension would be 50N right?
uhh no
for that case just write two equation (with fbd of either block) and solve
u get 66.67N
I think ur thinking that tension will be equal to the weight, that is not the case here as acceleration exists
Acceleration is upwards so the force upwards is more [if T=mg, then a=0]
ohh so if the monkey was just hanging doing nothing only then the tension would be equal to weight as its an equilibriumj/?
Yah if the system is in equilibrium and there is no acc, then the tension will be equal to weight
okay thanks
shall we close this?
