Answer #1

a)v^2=u^2+2as

v=0

a=-10m/s^2(since it is due to gravity in downward direction)

s=36m

u=26.56m/s

b)v=u+at

0=26.56-10t

Substituting values from above.

t=2.656s

    A particle is uncharged and is thrown vertically upward from ground level with a speed of 26.5 m/s. As a result, it attains a maximum height h. The particle is then given a positive charge +q and reaches the same maximum height h when thrown vertically upward with a speed of 29.9 m/s. The electric potential at the height h exceeds the electric potential at ground level. Finally, the particle is given a negative charge -q. Ignoring air resistance, determine...
