∫q =δδt = e average/Rδt =(δφ/δt)/Rδt =δφ/R = bδs/R = BLH/R
∴h=qR/BL.
Substitution number: q = 0.2c×1ω/(1t× 0.5) = 0.4m.
2) When gravity and ampere force are balanced, the speed is the maximum.
Suppose PQ just reaches the maximum speed Vmax at this time.
∫mg = BιL = BL E/R = BL blv max/R = B? l? Vmax/R
Vmax = manager /B? l? .
Substitution number: VMAX = 0.01kg× 9.8n/kg×1ω/(1t)? ×(0.5m)? = 0.392 m/s.
