Answer with Explanation:
We are given that
a.x=-0.2 m
Where
Net electric field=E+E'=4500+1237.5=5737.5 N/C
b.x=0.20 m
Net electric field=E-E'=4500-1237.5=3262.5 N/C
c.y=0.20 m
E=1237.5 N/C
Net electric field=
Answer:
Magnetic force, F = 0.24 N
Explanation:
It is given that,
Current flowing in the wire, I = 4 A
Length of the wire, L = 20 cm = 0.2 m
Magnetic field, B = 0.6 T
Angle between force and the magnetic field, θ = 30°. The magnetic force is given by :
F = 0.24 N
So, the force on the wire at an angle of 30° with respect to the field is 0.24 N. Hence, this is the required solution.
3.92N
Explanation:
Given mass:
Mass of bag = 400g
The mass of a substance is the amount of matter it contains.
Weight of a substance is the vertical force acting on a body in the presence of gravity.
Weight = mass x gravity
Since the mass of the bag is 400g;
Now we convert to kg
1000g = 1kg
400g = = 0.4kg
Weight of bag = 0.4kg x 9.8m/s²
Weight of bag = 3.92N
