Passive voice having two objects part 02

A charge Q is to be divided on two objects. What should be the values of the charges on the objects so that the force between the objects can be maximum?

An object may have

An object may have

A : The relative acceleration of two objects moving under the effect of gravity, only is always zero, irrespective of direction of motion. R : The acceleration of object moving under the effect of gravity have acceleration always in downward direction and is independent from size and mass of object.

Two objects slide over a frictionless horizontal surface The first object, mass m_(1)=5 kg, is propelled with a speed u=4.5m//s towards the second object, mass m_(2)=2.5 kg while is intially at rest. After the collision, both objects have velocities which are directed at theta=30^(@) on either side of the original line of motion of the first object. What are the final speed of the two object? Is the collision elastic or inelastic?

An eye can distinguish between two points of an object if they are separated by more than 0.22 mm when the object is placed at 25 cm from the eye. The object is now seen by a compound microscope having a 20 D objective and 10 D eyepiece separated by a distance of 20 cm. The final image is formed at 25 cm from the eye. What is the minimum separation between two points of the object which can now be distinguished?

Number of ways in which two persons A and B select objects from two different groups each having 20 different objects such that B selects always more objects than A (including the case when A selects no object) is (2^(40)-^(40)C_(21))//2.

Assertion: Mass is a property of one object alone, whereas weight results from the interaction of two objects. Reason: The weight of an object is proportional to its mass.
