Question 2

Two Tensile forces, each of magnitude F are acting at a point perpendicular to each other, then their resultant force will be :

Question 3

The bar AB weighs 10 kg per meter and is supported by cable AC and a pin at B. Reaction at B is (take g = 10 m/s²)

Question 4

A block of mass M is released from point P on a rough inclined plane with inclination angle θ, shown in the figure below. The co – efficient of friction is μ. If μ < tan θ, then the time taken by the block to reach another point Q on the inclined plane, where PQ = s, is

Question 5

A couple is formed when:

Question 7

When a body falls freely under gravitational force, it possesses __________.

Question 8

An elevator of mass 1000Kg attains an upward velocity of 4m/sec in two seconds with uniform acceleration. The tension (in N) in supporting cable will be (g=9.8m/sec²)

Question 9

A vegetable vendor weighing the vegetables using a weighing pan, the weight of the vegetables is lesser than the weights in the pan. The vendor holds the weighing scale with its hand thus applying some force. The forces thus analyzed forms a :
