Answer:
T =176 N
Explanation:
from diagram
F -(m_1+m_2_g) = (m_1+m_2_g)a
440 - (6+4)g = (6+4)a
a =\frac{440-10*9.8}{10}
a =34.2 m/s^2
frrom free body diagram of mass m2 = 4kg
T -m_2g =m_2a
T = m_2(g +a)
T = 4(9.81+34.2)
T =176 N
Answer:
(A). The flux is 0.336 N.m²/C
(B). The flux is zero.
Explanation:
Given that,
Length = 4.2 cm
Width = 4.0 cm
Electric field
Area vector is perpendicular to xy plane
(A). We need to calculate the flux
Using formula of flux
Where, E = electric field
A = area
Put the value into the formula
(B). Given electric field
We need to calculate the flux
Using formula of flux
Put the value into the formula
Here, The component of k is not given
So, the flux is
Hence, (A). The flux is -0.336 N.m²/C
(B). The flux is zero.
