The value of m1 is 9 g.
Explanation:
Complete statement:
A mobile is constructed of light rods and objects as shown in the figure. Determine the value of m1?
We are given that:
- Number of rods = 3
- To find: Mass of size particle =?
Solution:
m4 = 12.0 g
The formula to calculate torque:
τ = F x d
Here
F = force acting on the rod
D = distance from the point
Now the mass is given as;
(m4g)(3.00 cm) - (m1g)(4.00cm) = 0
m1 = (m4g)(3.00) / g (4)
m1 = (12 x 10) x (3) / 10 x 4
m1 = 120 x 3 / 40
m1 = 360 / 40 = 9 g
Thus the value of m1 is 9 g.
