Question

A particle, of mass 10⁻³ kg and charge 1.0 C, is initially at rest. At time t = 0, the particle comes under the
influence of an electric field ￫ E(t)=E₀ sin????t î, where E₀ = 1.0 NC⁻¹ and ???? = 10³ rad s⁻¹ . Consider the
effect of only the electrical force on the particle. Then the maximum speed, in m s⁻¹, attained by the particle
at subsequent times is ____________.

Answer 1

Nerf (trademarked in capitals as NERF) is a toy brand formed by the Parker Brothers and currently owned by Hasbro. Most of the toys are a variety of foam-based weaponry, with other Nerf products including balls for sports like American football, basketball and baseball. The most notable of the toys are their dart guns (referred to by Hasbro as "blasters") that shoot ammunition made from Nerf foam. Since many such items were released during the 1970s, Nerf products often feature bright neon colors and soft textures similar to the flagship Nerf ball. Their slogan, which has been frequently used since advertising in the 1990s, is "It's Nerf or Nothin'!". Annual revenues under the Nerf brand are approximately US$400 million.[1]
