Explanation of Solution

Given info:

The given table is,

    nLnrnKnEnvn
    n= 1
    n= 2
    n= 3
    n= 4
    n= 5

Formula used:

The expressions for angular momentum, speed, orbital radius, kinetic energy and total energy are:

  Ln=nh2πrn=n2h24π2mke2Kn=mk2e42n22En=mk2e42n22vn=2πke2nh

Calculation:

All values are given in SI unit. The values of different constants as considered for calculation are
  k=8.99×109 Nm2Coulomb-2m=9.11×1031 kgh=1.055×10-34 Joule-sece=1.6×10-19 Coulomb

The force of the quadriceps (Fq) and force of the patellar tendon (Fp) is identical (i.e., 1000 N each). In the figure below angle in blue is Θ and the in green is half Θ (i.e., Θ/2). A) Calculate the patellar reaction force (i.e., R resultant vector is the sum of the horizontal component of the quadriceps and patellar tendon force) at the following joint angles: you need to provide a diagram showing the vector and its components for each part. a1) Θ = 160 degrees, a2) Θ = 90 degrees.
