An object of mass 82kg is accelerated upward at 3.2m/s/s. what force is required

Physics

F = m · a

In order to accelerate 82 kg upward at the rate of 3.2 m/s², a NET upward force of (82kg · 3.2m/s²) =  262.4 Newtons is required.

But if the object is on or near the surface of the Earth, then there's a downward force of (82kg · 9.8m/s²) = 803.6 N already acting on it because of gravity.

So you need to apply (803.6N + 262.4N) = <em>1,066 Newtons UPward</em>, in order to cancel its own weight and accelerate it upward at that rate.

Liula [17]

Answer:

The magnitude of the electric field at distance r from the point charge q is \dfrac{kq}{r^2}

Explanation:

Suppose, Find E(r), the magnitude of the electric field at distance r from the point charge q.

We know that,

The electric field is proportional to the point charge and inversely proportional to the square of the distance from the charge point .

In mathematically,

E=\dfrac{kq}{r^2}

Where, q = charge point

R = distance from charge point

Hence, The magnitude of the electric field at distance r from the point charge q is \dfrac{kq}{r^2}

Determine the force between two long parallel wires, that are separated by a dis- tance of 0.1m the wire on the left has a curre
valina [46]

Answer:

3 x 10^-4 N/m

Attractive

Explanation:

r = 0.1 m, i1 = 10 A, i2 = 15 A

The force per unit length between two parallel wires is given by

F = \frac{\mu _{0}}{4\pi }\times \frac{2i_{1}i_{2}}{r}

F = \frac{10^{-7}\times 2\times 10\times 15}{0.1}

F = 3 x 10^-4 N/m

Thus, the force per unit length between two wires is 3 x 10^-4 N/m, the force is attractive in nature because the direction of flow of current in both the wires is same.
