An electron and a position are released from (0, 0, 0) and `(0, 0, 1*5R)` respectively, in a uniform magnetic field `vecB=B_0hati`, each with an equal momentum of magnitude `p=eBR`. Under what conditions on the direction of momentum will the orbits be non-intersecting circles?

Explanation

To solve the problem, we need to determine the conditions under which the orbits of an electron and a positron, released from different points in a uniform magnetic field, do not intersect.

### Step-by-Step Solution:

1. **Understanding the Setup**:
- The electron is released from the origin (0, 0, 0).
- The positron is released from the point (0, 0, 1.5R).
- Both particles have equal momentum \( p = eBR \) and experience a magnetic field \( \vec{B} = B_0 \hat{i} \).
