This answer of the strength and directions of the magnetic field is a
Explanation:
It is given that,
Relativistic Mass of the stone, m₀ = 0.6
Mass,
Relativistic mass is given by :
.........(1)
Where
c is the speed of light
On rearranging equation (1) we get :
v = 0.61378 c
or
v = 0.6138 c
So, the correct option is (c). Hence, this is the required solution.
Answer:
a= 2 m/s^2
Explanation:
take to the right as positive
let Ftot be the total forces acting on the box , m be the mass of the box and a be the acceleration of the box.
Ftot = 10 - 2 = 8 N
and,
Ftot = ma
a = Ftot/m
= 8/4
= 2 m/s^2
therefore, the acceleration of the box is of magnitude of 2 m/s^2.
