By Newton's 3rd law: That for every action there is an equal and opposite reaction.
So if force on one mass is 4N, then the force on the other mass is -4N.
Answer:
Explanation:
Newton’s second law states that the acceleration a of an object is proportional to the force F acting on it is inversely proportional to its mass m. The mathematical expression for the second law of motion is given by :
F = m × a
F is the applied force
m is the mass of the object
a is the acceleration due to gravity
We need to find the dimensions of force. The dimension of force m and a are as follows :
So, the dimension of force F is, . Hence, this is the required solution.
Answer:
Explanation:
the electric field between the plates is uniform and given by
E⃗ =(120N/C) j
So electric field is along y - axis
Force on electron
F_y = 1.6 x 10⁻¹⁹ x 120
a_y ( acceleration )= ( 1.6 x 10⁻¹⁹ / 9.1 x 10⁻³¹ ) x 120
a_y = 21.1 x 10¹²
a = 21.1 x 10¹² j
time to reach x = 2 cm = 2 x 10⁻² m
t = 2 x 10⁻² / 2.5 x 10⁵
= .8 x 10⁻⁷
= 8 x 10⁻⁸ s
velocity along y axis after time 8 x 10⁻⁸ s
= u + at
= 5 x 10³ + 21.1 x 10¹² x 8 x 10⁻⁸
= 5 x 10³+ 168.8 x 10⁴
= .05 x 10⁵ + 16.88 x 10⁵
= 16.93 x 10⁵
resultant velocity
= √( 2.5 x 10⁵ )² + ( 16.93 x 10⁵)²
= 17.11 x 10⁵ m /s
Answer: Choose the normal force acting between the object and the ground. Let's assume a normal force of 250 N.
Determine the friction coefficient.
Multiply these values by each other: 250 N * 0.13 = 32.5 N .
You just found the force of friction!
