    Solid insultaing sphere electric field

    Homework Statement A solid insulating sphere of radius R carries a charge per unit volume of p. Use Gauss' law to find an expression for the eletric field on a spherical surface of radius R/2 ie: inside the sphere. Homework Equations Gauss' Law = (Net Flux = Q / Eo) Volume of a Sphere...

    Finding Velocity given angle and distance.

    ok so is this right, Vo = \sqrt{(g*d)/(2 sin Theta*cos Theta)} Vo = \sqrt{(9.8*60) / (2 sin 45*cos 45)} Vo = 24.24
  4. O

    Finding Velocity given angle and distance.

    Ok cool, so is Vy cos 45 = 0.707? so then Vy = Vx = 0.707?
  5. O

    Finding Velocity given angle and distance.

    Homework Statement The questions is, that if you throw something at exactly 45 degrees above the horizontal and it travels 60 m before hitting the ground what's it velocity? Homework Equations Physic's equation, see below The Attempt at a Solution Horizontal Component Vh = cos...
