FrozenT [24]

Answer:

T1 = 490.5 [N], T2 = 490.5[N]

Explanation:

First, we must draw a free body diagram of the steel ball hanging and the two wires holding it as well as the angle forming the wires between them.

The free-body diagram can be seen in the attached image.

As the cables are symmetrical with respect to the vertical axis, the force in cables 1 and 2 is equal, so when performing a force sum equal to zero on the Y-axis, we can find the force value of any cable.

The solution of the equations can be seen in the attached image

kvasek [131]

Answer: 1361.11\ N/C,\text{upward}

Explanation:

Given

Mass of particle is m=2.5\ gm

Charge of particle is q=18\ \mu C

Electrostatic force must balance the weight of the particle

\lim_{n \to \infty} a_n \Rightarrow mg=qE\\\\\Rightarrow E=\dfrac{2.5\times 9.8\times 10^{-3}}{18\times 10^{-6}}\\\\\Rightarrow E=1361.1\ N/C

Direction of the electric field is in upward direction such that it opposes the gravity force.

Dominik [7]

Answer:

Explanation:

s = 50 t^2

Differentiate both sides with respect to t

ds/dt = 50 x 2 t

ds/dt = 100 t

Substitute t = 10 second

ds/dt = 100 x 10

ds/dt = 1000 m/s

thus, the rate of change of elevation is 1000 m/s.
