i. Clockwise moment = 10cm ⨯ 10N + 30cm ⨯ 30N = 1000Ncm. ii.Anticlockwise moment = 40cm ⨯ 60N = 2400Ncm. iii. Here, Clockwise moment is not equal to anticlockwise moments. So, lever is not .....
Now you need to check. Put x = -3 in √(x2 + 3 + x) = 3. We get, √((-3)2 + 3 - 3) = 3. or, √(9 ) = 3. or, 3= 3 (True.) Again, put x = 2 in √(x2 + 3 + x) = 3., .....
