An electron enters a parallel plate capacitor with horizontal speed u and is found to deflect by angle `theta` on leaving the capacitor as shown. It is found that an `theta = 0.4` and gravity is negligible

If the initial horizontal speed is doubled, then will be -

An electron enters a parallel plate capacitor with horizontal speed u and is fond to deflect by angle theta on leaving the capacitor as shown. It is found that tan theta = 0.4 and gravity is negligible If the initial horizontal speed is doubled, then tan theta will be

A particle is projected at an angle theta with an initial speed u .

A man is running up an inclined plane ( making an angle theta with the horizontal ) with a speed u. Rain drops falling at an angle alpha with the vertical appear to the man as if they are falling at an angle of 45^(@) with the horizontal . The speed of the rain drops is

A particle is fired from a point on the ground with speed u making an angle theta with the horizontal.Then

A particle is fired from a point on the ground with speed u making an angle theta with the horizontal.Then

A stone is thrown with a velocity v at an angle theta with the horizontal.Its speed when it makes an angle beta with the horizontal is

If an electron enters a space between the plates of a parallel plate capacitor at an angle theta_(1) with the plates and leaves at an angle theta_(2) to the plates, the ratio of its kinetic energy while entering the capacitor to that while leaving will be
