Solve or answer........................................................

Answer 1

Step-by-step explanation:

Moments on either side of the pivot must be equal

Let g = gravity acceleration

Let m = unknown mass B

i) 4g[0.5] = mg[0.1]

m = 20 kg

ii) Clockwise

iii) The moment of the A block is decreased when moved toward the pivot. The now greater moment of block B causes a clockwise movement.
