Answer 1

Answer:

block of mass 35 kg

resting on a table. The table is so rough that

it offers a self adjusting resistive force 10%

of the weight of the block for its sliding

motion along the table. A 20 kg wt load is

attached to the block and is passed over a

pulley to hang freely on the left side. On the

right side there is a 2 kg wt pan attached to

the block and hung freely. Weights of 1 kg

wt each, can be added to the pan. Minimum

how many and maximum how many such

weights can be added into the pan so that

the block does not slide along the table?

[Ans: Min 15, maximum 21].
