Answer:
The fulcrum of the metre stick is at the 40 cm mark
100 g * 10 cm = 1000 g-cm clockwise torque
x * 30 cm = 1000 gm-cm = counterclockwise torque for balance
X = 1000 / (40 -10) = 1000 / 30 = 33.3 gm at 10 cm to balance
Answer:
C evaluating the solution
Answer:
Explanation:
Given
radius of Planet is equal to radius of Earth
Weight of body on Planet
where m=mass of body
Weight of body on earth
acceleration due to gravity is given by
where G=gravitational constant
M=mass of Planet
r=radius of planet
for earth
for planet
substituting these values in and
divide 1 and 2
