✅ The correct answer is option B.
For any system of coplaner forces, the condition of equilibrium is that the
algebraic sum of the horizontal components of all the forces should be zero
algebraic sum of the vertical components of all the forces should be zero
algebraic sum of moments of all the forces about any point should be zero
all of the above
✅ The correct answer is option D.
If the body falls freely under gravity, then the gravitational acceleration is taken as
+8.9 m/s2
-8.9 m/s2
+9.8 m/s2
-9.8 m/s2
✅ The correct answer is option C.
If P is the force acting on the body, m is the mass of the body and a is the acceleration of the body, then according to Newton’s second law of motion,
P + m.a = 0
P – m.a = 0
P x m.a = 0
P/m.a = 0
✅ The correct answer is option B.
