Velocity and acceleration vectors of charged particle moving perpendicular to the direction of magnetic field at a given instant of time are `vecV=2hati + c hatj` and `veca= 3hat i+4hat j` respectively. Then value, of c is

Velocity and acceleration vectors of charged particle moving perpendicular to the direction of magnetic field at a given instant of time are vecv=2hati+chatj and veca=3hati+4hatj respectively. Then that value of 'c' is

Velocity and acceleration vectors of charged particle moving perpendicular to the direction of magnetic field at a given instant of time are vartheta= 2hat(i) + c hat(j) and bar(a) = 3 hat(i) + 4 hat(j) respectively. Then the value of .c. is

Velocity and acceleration vectors of charged particle moving perpendicular to the direction of magnetic field at a given instant of time are vartheta= 2hat(i) + c hat(j) and bar(a) = 3 hat(i) + 4 hat(j) respectively. Then the value of .c. is

Velocity and acceleration vectors of a charged particle moving in a magnetic field at some instant are vec(v)=3hat(i)+4hat(j) and vec(a)=2hat(i)+xhat(j) . Selcet the wrong alternative.
