Question

17. A block of mass 200 kg is set into motion on a frictionless
horizontal surface with the help of frictionless pulley and a
rope system as shown in figure. What horizontal force F
should be applied to produce in the block an acceleration
of 1 ms-2?
a = 1 ms-2
(b) 100 N
(C) 200 N
(a) 50 N
(d) 10 N
​

Answer 1

Answer:

200N

Explanation:

given:-

m=200kg

a = 1 ms-2

F=ma

=200kg ×1ms-2

=200N

Answer 2

Explanation:

T = 2F

T=ma =200×1= 200N

2F=200N

F =100N
