As we know
q is the charge on the electron = C
B is the magnetic field in Tesla = T
r is the radius of the circle = m
mass of the electrons = Kg

Answer:
The phase difference between these two waves is 141.1⁰
Explanation:
The displacement of the wave is given as;
Amplitude, A = 2yₓCos(¹/₂Φ)
Since the amplitude of the combination is 1.5 times that of one of the original amplitudes = yₓ = 1.5 × A = 1.5A
A = 2(1.5A)Cos(¹/₂Φ)
A = 3ACos(¹/₂Φ)
¹/₃ = Cos(¹/₂Φ)
(¹/₂Φ) = Cos ⁻(0.3333)
(¹/₂Φ) = 70.55°
Φ = 141.1°
The phase difference between these two waves is 141.1⁰
