Which of the following is true about this lever?

it will rotate clockwise.
it will rotate counter-clockwise.
it is balanced and will not rotate.

As we can see here the lever has two forces at two ends

1. 300 N

2. 200 N

now we need to find the Torque on the lever about the fulcrum

so we will have

1. clockwise torque due to force at right end is

2. counterclockwise torque due to force at left end

so as per above calculations we can see that net torque on the lever is clockwise as it has more torque in clockwise direction

so it will rotate clockwise

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

answer; how far out of place which the object finished relative to the starting location;
