MCQ

A suitable unit for gravitational constant is

A
$kg{\rm{ - }}\,m\;{\sec ^{ - 1}}$
B
$N\;{m^{ - 1}}\sec $
✓
$N\,\,{m^2}\,k{g^{ - 2}}$
D
$kg\,m\,{\sec ^{ - 1}}$

✓

Answer

Correct option: C.

$N\,\,{m^2}\,k{g^{ - 2}}$

c
(c) $F = \frac{{G{m_1}{m_2}}}{{{d^2}}};$

$\therefore $ $G = \frac{{F{d^2}}}{{{m_1}{m_2}}} = N{m^2}/k{g^2}$

A horizontal force of $129.4 \,N $ is applied on a $10\, kg$ block which rests on a horizontal surface. If the coefficient of friction is $0.3$, the acceleration should be ....... $m/s^2$

When a body slides down from rest along a smooth inclined plane making an angle of $30^{\circ}$ with the horizontal, it takes time $T$. When the same body slides down from the rest along a rough inclined plane making the same angle and through the same distance, it takes time $\alpha {T}$, where $\alpha$ is a constant greater than $1 .$ The co-efficient of friction between the body and the rough plane is $\frac{1}{\sqrt{{x}}}\left(\frac{\alpha^{2}-1}{\alpha^{2}}\right)$ where ${x}=..... .$
