The roughness of the surface, the mass of the object, and the area of contact.
Answer:
charge will be equal to
Explanation:
We have given mass of the particle m = 1.45 gram = 0.00145 kg
Acceleration due to gravity ![g=9.8m/sec^2](https://tex.z-dn.net/?f=g%3D9.8m%2Fsec%5E2)
Electric field E = 700 N/C
Electric force will be equal to
, here q is charge and E is electric field
For particle to be stationary this force must be equal to force due to gravity , that is mg force
So qE = mg
![q=\frac{mg}{E}=\frac{0.00145\times 9.8}{700}=2.03\times 10^{-5}C](https://tex.z-dn.net/?f=q%3D%5Cfrac%7Bmg%7D%7BE%7D%3D%5Cfrac%7B0.00145%5Ctimes%209.8%7D%7B700%7D%3D2.03%5Ctimes%2010%5E%7B-5%7DC)
So charge will be equal to
Answer:
huh what do u want tho its nothing bad
Explanation:
Answer:
0.208 N
Explanation:
Parameters given:
Current, I = 2A
Angle, A = 60°
Magnetic field strength, B = 0.2 T
Length, L = 0.6 m
Magnetic force is given as:
F = I * L * B * sinA
F = 2 * 0.6 * 0.2 * sin60
F = 0.24 * sin60.
F = 0.208 N
Answer:
Force = 0.42 Newton
Explanation:
Given the following data;
Spring constant, k = 2.1
Extension, e = 0.2m
To find the force, we would use the formula below;
Force = spring constant * extension
Force = 2.1 * 0.2
Force = 0.42 Newton
