Two masses $m_1$ and $m_2\, (m_1 < m_2)$ are released from rest from a finite distance. They start under their mutual gravitational attraction
acceleration of $m_1$ is more than that of $m_2$
acceleration of $m_2$ is more than that of $m_1$
centre of mass of system will remain at rest in all the reference frame
total energy of system does not remain constant
Weight of a body of mass m decreases by $1\%$ when it is raised to height $h$ above the earth’s surface. If the body is taken to a depth h in a mine, change in its weight is
Spot the wrong statement :The acceleration due to gravity $‘g’$ decreases if
At what height over the earth's pole, the free fall acceleration decreases by one percent ........ $km$. (assume the radius of earth to be $6400 \,km$)
${g_e}$ and ${g_p}$ denote the acceleration due to gravity on the surface of the earth and another planet whose mass and radius are twice as that of earth. Then
A rocket is launched with velocity $10\, km/s$. If radius of earth is $R$, then maximum height attained by it will be
