A man is carrying a block of a certain substance (of density $1000 \,kg{m^{ – 3}}$) weighing $1 \,kg$ in his left hand and a bucket filled with water and weighing $10 \,kg$ in his right hand. He drops the block into the bucket. How much load does he carry in his right hand now  ……….. $kg$

Inertia is that property of a body by virtue of which the body is

An object will continue moving uniformly until

For ordinary terrestrial experiments, the observer in an inertial frame in the following cases is

A stone of mass $0.25\; kg$ tied to the end of a string is whirled round in a circle of radius $1.5 \;m$ with a speed of $40\; rev./min$ in a hortzontal plane.the speed of the stone is increased beyond the maximum permissible value, and the string breaks suddenly, which of the following correctly describes the trajectory of the stone after the string breaks :

$(a)$ the stone moves radially outwards,

$(b)$ the stone flies off tangentially from the instant the string breaks,

$(c)$ the stone flies off at an angle with the tangent whose magnitude depends on the speed of the particle ?
