c.) Given the values L = 9cm, q = 89nC, σ=3.4μC/m2, and m = 3.8g, enter a numeric value for the angle θ in degrees. d.) Given the values L = 9cm, q = 89nC, σ=3.4μC/m2, and m = 3.8g, enter a numeric value for the tension in the string, FT, in newtons.
A small sphere with mass mm and charge q is attached to one end of a string with length L and tension FT. The other end of the string is attached to a wall which has surface-charge density σσ. The angle between the string and the wall is θ, as shown in the drawing.
Need help with parts c and d. Parts a and b were identified as correct but I keep getting wrong answers for c and d.
a.) Fxnet = - FT sin(θ) + q σ/2 /ε0
b.) Fynet = FT cos(θ) - m g
c.) Given the values L = 9cm, q = 89nC, σ=3.4μC/m2, and m = 3.8g, enter a numeric value for the angle θ in degrees.
d.) Given the values L = 9cm, q = 89nC, σ=3.4μC/m2, and m = 3.8g, enter a numeric value for the tension in the string, FT, in newtons.
