Answer:
2.17 A
Explanation:
The magnetic field due to a circular current carrying coil is given by
B = k x 2i / r
For i = 7 A, r = 0.097 m, clockwise
B = k x 2 x 7 / 0.097 = 144.33 k (inwards)
The direction of magnetic field is given by the Maxwell's right hand thumb rule.
The magnetic field is same but in outwards direction as the current is in counter clockwise direction. Let the current be i.
Now, r = 0.03 m, B = 144.33 K, i = ?
B = k x 2i / r
144.33 K = K x 2 x i / 0.03
i = 2.17 A
Newton's first law of motion is connected with inertia :)
according to newton's second law , net force on an object is the product of mass of the object and the acceleration of the object. the formula is given as
F = ma where F = net force , m = mass and a = acceleration
so acceleration can be given as
a = F/m
for same net force , the acceleration depends on the mass of the object .
greater the mass , smaller will be the acceleration and vice versa.
Since the mass of electron is smaller as compared to the mass of proton, hence the electron will accelerate more as compared to proton.
A) The electron will accelerate more than the proton
Answer:
Vo (vertical) = Vo sin 30 = 30 m/s / 2 = 15 m/s
Vo (horizontal) = Vo cos 30 = .866 30 m/s = 26 m/s
